Level crossing

A level crossing is an intersection where a railway line crosses a road or path, or in rare situations an airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), railroad crossing (chiefly North American), grade crossing, road through railroad, criss-cross, train crossing, and RXR (abbreviated).
There are more than 100,000 level crossings in Europe and more than 200,000 in North America. 
History.
The history of level crossings depends on the location, but often early level crossings had a flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings became commonplace in many areas, as they protected the railway from people trespassing and livestock, and they protected the users of the crossing when closed by the signalman/gateman. In the second quarter of the 20th century, manual or electrical closable gates that barricaded the roadway started to be introduced, intended to be a complete barrier against intrusion of any road traffic onto the railway. Automatic crossings are now commonplace in some countries as motor vehicles replaced horse-drawn vehicles and the need for animal protection diminished with time. Full, half or no barrier crossings superseded gated crossings, although crossings of older types can still be found in places. 
In rural regions with sparse traffic, the least expensive type of level crossing to operate is one without flagmen or gates, with only a warning sign posted. This type has been common across North America and in many developing countries.
Some international rules have helped to harmonize level crossing. For instance, the 1968 Vienna Convention states (chapter 3, article 23b) that:
This has been implemented in many countries, including countries which are not part of the Vienna Convention.
Safety.
Trains have a much larger mass relative to their braking capability, and thus a far longer braking distance than road vehicles. With rare exceptions, trains do not stop at level crossings and rely on vehicles and pedestrians to clear the tracks in advance.
Level crossings constitute a significant safety concern internationally. On average, each year around 400 people in the European Union and over 300 in the United States are killed in level crossing accidents. Collisions can occur with vehicles as well as pedestrians; pedestrian collisions are more likely to result in a fatality. Among pedestrians, young people (5–19 years), older people (60 years and over) and males are considered to be high risk users.
As far as warning systems for road users are concerned, level crossings either have "passive" protection, in the form of various types of warning signs, or "active" protection, using automatic warning devices such as flashing lights, warning sounds, and barriers or gates. In the 19th century and for much of the 20th, a written sign warning "Stop, look, and listen" (or similar wording) was the sole protection at most level crossings. Today, active protection is widely available, and fewer collisions take place at level crossings with active warning systems. Modern radar sensor systems can detect if level crossings are free of obstructions as trains approach. These improve safety by not lowering crossing barriers that may trap vehicles or pedestrians on the tracks, while signalling trains to brake until the obstruction clears (however, they cannot prevent a vehicle from moving out onto the track once it's far too late for the locomotive to slow even slightly).
At railway stations, a pedestrian level crossing is sometimes provided to allow passengers to reach other platforms in the absence of an underpass or bridge, or for disabled access. Where third rail systems have level crossings, there is a gap in the third rail over the level crossing, but this does not necessarily interrupt the power supply to trains since they may have current collectors on multiple cars.

Traffic signal preemption.
Traffic signal-controlled intersections next to level crossings on at least one of the roads in the intersection usually feature traffic signal preemption. Approaching trains activate a routine where, before the train signals and gates are activated, all traffic signal phases go to red, except for the signal immediately after the train crossing, which turns green (or flashing yellow) to allow traffic on the tracks to clear (in some cases, there are auxiliary traffic signals prior to the railroad crossing which will turn red, keeping new traffic from crossing the tracks. This is in addition to the flashing lights on the crossing gates). After enough time to clear the crossing, the signal will turn. The crossing lights may begin flashing and the gates lower immediately, or this might be delayed until after the traffic light turns red.
The operation of a traffic signal, while a train is present, may differ from municipality to municipality. In some areas, all directions will flash red, turning the intersection into an all-way stop. In other areas, the traffic parallel to the railroad track will have a flashing yellow for the duration of the train while the other directions face a flashing red light for the duration of the train. Still in other areas, the traffic parallel to the railroad track will have a green light for the duration of the train while the other directions face a red light for the duration of the train. Further still in other areas can traffic lights operate relatively normally with only the blocked direction turning red for the duration of the train.
Experimented cameras.
In France, on some level crossings cameras have been experimented to obtain images to improve understanding of the crash accident when a technical investigation occurs.
In northern England and in the territory 31 high technology cameras have been installed.
In Australia, 4 cameras have been installed at level crossing.
Crossings around the world.
Europe.
There were 108,196 level crossings in the European Union Member States in 2014. On average there are just under 0.5 level crossings per line-kilometres in the EU.
53% of all those level crossings are active level where users are protected from or warned of the approaching train by devices activated when it is unsafe for the user to traverse the crossing.
The remaining 47% of level crossings are unprotected. 28% of railway fatalities are from level crossing related incidents.
Albania.
Albanian level crossings are uncommon, but do have red lights and barriers that may be automatic. Many crossings are still manual, but some are automatic and have bells.
Austria.
Austrian level crossings are similar to German crossings, in that they have either a single or double light, not always with automatic barriers that lower when a train approaches. The crossings with two lights (one amber, one red) are the more modern, replacing old single red light crossings.
Belgium.
Automatic level crossings in Belgium have two red lights, a "moon-white" light, electronic (previously mechanical) bells and (usually) barriers. The white light flashes for half a second at regular intervals to inform drivers and pedestrians that they can cross the level crossing, and that the signal is in working order. In some cases the white light is absent; in that case overtaking on the crossing is not allowed. The bells ring until the barriers are fully lowered and then stop. If barriers are absent the bell continues ringing throughout. Also in use with two or three lights and without barriers on tramways at De Panne, Zwijndrecht, Anderlues, Ghent, and MIVB Line 44(only here with bells).
At a level crossing, any overhead electric power cables must also cross. This led to a conflict where a mainline railway that crossed one of the country's once extensive interurban tram lines ("vicinal", "buurtspoorweg"/"vicinaux") was electrified. In at least one location, this led to the tram overhead being dismantled.
Bosnia and Herzegovina.
Bosnia and Herzegovina level crossings uses two red lights in a triangle, much like the crossings in Serbia, Switzerland and Croatia. Crossings without lights or gates uses white target boards.
Croatia.
Croatian level crossings are similar to Slovenian and Bosnian crossings in that the lights are composed of red lights in a triangle. Many crossings are automatic with barriers and bells.
Czech Republic and Slovakia.
Level crossings in Czech Republic and Slovakia use a sign on the lights that reads "Pozor Vlak" (Attention - Train) to warn people of the crossing. The crossbuck of a Slovak crossing is on a standard sign, while the Czech crossbuck is a cutout sign. The lights are similar to the Belgian crossings in that they have two red lights and sometimes a white light, which means the driver can go up to 50 km/h, rather than 30 km/h, with half barriers. On some crossings, the space for a white light is provided but no light is there, because in newer legislation it is taken as dangerous element that should not be used to positively change drivers' speed. Sometimes a yellow outline surrounds the crossbucks for increased visibility at night. Some of the oldest crossings, do not feature lights, but do have bells and gates. Some older (though newer than those mentioned, dubbed SSSRs) crossings are in a design similar to American or UK crossings, and feature electromechanical buzzers as opposed to bells. Newer crossings are similar to those of the UK.
More recently, Slovak legislation has called for the phase out of the Czech crossing in favor of German counterparts. The newest crossings already feature German bells, lights (though they are in the Czech style as opposed to German) and gates, where they are needed.
Denmark.
The crossings in Denmark have white and red saltires and crossing lights in the shape of a triangle coloured red, white and blue with a flashing red light in the center. Most of the equipment is from Dansk Signal Industri but recently Scheidt & Bachmann's crossing equipment has started being used. Most crossings are only half barrier, and bells stop sounding when gates have lowered on almost all crossings, if the crossings has no gates, the bells sound until the train has passed. Unprotected crossings only have saltires and sometimes a sign saying "Se Efter Tog". Some older guarded crossings do not have the saltires.
Estonia.
Most protected crossings are equipped with LED-lights. Non-gated crossings have a crossbuck fitted, but gated ones do not. All gated crossings have half-barriers though some are marginally longer than others. Alarms may vary. Many crossings use the same alarm sound used on Polish crossings, very rarely fire alarms, sometimes a simple high pitch beep. Some non-gated crossings have a white flashing light that flashes when the crossing is inactive. In less populated areas crossings are fitted with just a crossbuck and sometimes a stop sign. A few USSR era signals still remain, however due to their obsolescence they are being replaced.
Finland.
In Finland, level crossings with warning lights have the more common red and a white light that flashes except when the red flash. Most, but not all, crossings with lights also have barriers. Full-length barriers are usually used only for pedestrian and bicycle lanes. Half-length barriers are used for motor roads, to avoid the risk of a vehicle being trapped on the tracks between the barriers. Bells begin to ring when the red lights start flashing and usually stop when the barriers have come down. Red-and-yellow crossbucks are used on both controlled and uncontrolled level crossings. If there are two or more tracks, the lower part of the cross is doubled. Only minor agricultural crossings may have no signs at all. On bigger roads there are usually also approach signs. Finnish level crossings are the sixth safest in Europe. Finland's state railway system has almost 3000 level crossings, according to TraFi. In Finland over the course of railway history many level crossing accidents have occurred, in comparison to Scandinavian countries. In Finland the maximum speed for trains on the rails with level crossings is 140 km/h.
France.
French level crossings usually have a single red light on a circle backboard, bells and automatic half barriers (11 200 out of 15 300). When activated, the red light flashes, the bells ring, and the barriers come down. Due to the Allinges 2008 crash, since 2017 the law plans the possibility to add extra blinking red light, when red light risks not being visible. French level crossings with more than one track have a sign saying "un train peut en cacher un autre" (a train can hide another train).
As of 2016 France has level crossings (by comparison, there were in 1938 and in 1980). Of these, less than 0.4% are on national roads, 31.4% are on departmental roads and 68.2% are on town roads. The high-speed train lines are built with no level crossings, but high-speed trains are also used on classical railway lines and exposed there to level crossing accidents.
In 2015, 100 crashes occurred at French level crossings, causing 26 fatalities. These crashes are usually caused by misuse, e.g., trying to pass as the barriers are down or are closing, in violation of the French traffic code.
Germany.
German crossings use yellow and red lights and a bell/alarm (some crossings do not have these though) to indicate that the crossing is active. When activating a preliminary yellow light flashes which is followed by a red light that stays lit until the crossing has been cleared by the incoming train. Most of these crossings have a lightning symbol on the crossbucks, to indicate that there are overhead cables. Some German railroad crossings have a white "tic-tac" crossing radar to detect obstacles on the tracks. Older crossings have a single red light on a square backboard with a red and white border. On older crossings, if more than one train is coming, a different bell will sound and a sign reading "2 Züge" ("2 trains") will flash.
Hungary.
In Hungary, level crossings mostly do not have audible tones, and some also do not have lights. Full barriers usually do not have lights, but have an audible warning. Crossings equipped with lights are common. A newer solution is a crossing equipped with half-barriers and LED-lights. A unique type of level crossings in Hungary have a sign saying "10 percen túl is zárva tartható" (can be kept closed for more than 10 minutes).
Ireland.
Irish level crossings are similar to UK level crossings, in that they have a preliminary amber light before the red lights start flashing and the barriers descend. Crossings are the same on the whole island of Ireland, and are either of the old gated variant, or are automatic. Ireland has automatic crossings that have full barriers. The audible alarms are unique to the country.
Isle of Man.
Isle of Man level steel railway crossings are based on the variants used in the UK and Ireland, but notable differences is that most crossings uses the vertical signals that have red flashing lights on the top and bottom, with the amber preliminary light in the middle. No crossbucks. Other crossings that don't have gates or lights, mostly uses a target board sign featuring the crossbucks. At some crossings the old manual gates are still in use. On the Manx Electric Railway are the same as in the UK in use. Without barriers. Some crossings have crossbucks only. The Snaefel Electric Railway has only crossbucks.
Italy.
Level crossings in Italy, much as in the rest of Europe, can be manned, unmanned, manual, or automated. In the Italian highway code, level crossings are called Passaggi a Livello, often abbreviated to "P/L" on road markings. Some level crossings have a sign saying "stop con segnale rosso" (stop with red signal). The crossing can be composed of single or double red lights depending on the type of barriers, mechanical or electrical barriers and, on older ones, a rotating crossbuck.
Latvia.
In Latvia, level crossings are similar to the variants used in Estonia and Russia. Protected crossings with gates have crossing gates similar to the ones used in Poland. Crossings without gates have a flashing white light, but some crossings don't have this feature. Alarms that sound varies at different locations; some crossings have audible tones similar that of a car alarm.
Newly refurbished crossings have updated warning lights that are similar to Polish level crossings. The bells at some of these crossings ring faster than the others.
Lithuania.
Level crossings in Lithuania usually have 2 flashing red lights and sometimes one white flashing light to indicate that the crossing is clear. Many crossings also have barriers. They use signage similar to that of Russia's.
Following ongoing refurbishment at many crossings, brand new crossings lights similar to the ones in Latvia are used, others have updated flashing lights with new e-bells that are also used in Germany. Some crossings have been rebuilt to include multiple gates for both road and pedestrian traffic. Newly installed electronic warning sign reading "Atsargiai Traukinys!" (Caution Train!) are also used as well.
Luxembourg.
Luxembourg uses two flashing red lights and double barriers at many level crossings. The alarms and crossing gates are based on the variants used in Germany.
Due to the location and terrain, a yellow sign reading "Un train peut en cacher un autre (One train can hide another)" is present at most locations. 
Moldova.
Moldova's level crossings are very similar to Russian level crossings, with the two red lights, but, like the Romanian level crossings, have an intermittent white light that flashes when there are no trains approaching and the system is working perfectly. The bells are very loud, just like Russian bells.
Montenegro.
Montenegro's level crossings have lights with a red border, yellow in the middle and two lights at the bottom. They can be gated or ungated. Some may have just an X on them while the others with the lights have an X and a bell. Many crossings over electrified railway lines have height restrictions due to the low cables.
Netherlands.
Most level crossings have half barriers, mechanical or electrical bells, and double (or sometimes single) red lights. The lights flash alternately, as do the ones on the barriers. Those for pedestrians with an active warning system have full barriers. One level crossing in Roermond is still operated remotely by staff from a traffic control centre, using cameras; this crossing has full barriers, no bells and has a system to detect a vehicle which has been trapped; in this case the exit barriers are opened. Crossings with little road traffic and/or little rail traffic have no alarm, just warning signs. There are no level crossings where trains routinely run at over 140 km/h. Most level crossings have a sign saying "WACHT" (WAIT).
Warning lights and bells are activated when the train is about 1 km before the crossing, depending on line speed. 5 seconds later the barriers start closing, which takes about 10 seconds. When the barriers have closed, the bells are often set less loud. Lights and bells are stopped when the barriers have raised again. As passive warning signs there are red and white striped fences, red and white saltires for single tracks (doubled in case of two or more tracks) and sometimes advanced warning signs at 80, 160 and 240 metres.
When there is a station shortly before the level crossing and an intervening signal, the signal may remain red and the crossing kept open until the train approaches the station. The crossing would then close after a delay, allowing the signal to be cleared.
North Macedonia.
Level crossings in North Macedonia look similar to those in Serbia, but are different due to how the lights turn off when both gates shut fully.
Norway.
In Norway, level crossings have red and white crosses with a similar light system to German crossings, although the yellow light shines and then the single red light flashes, as do the lights on the barriers.
From 1998 to 2008 the Norwegian rail administration ("Jernbaneverket") removed about 1000 level crossings, leaving about 3500 still in use. is the maximum speed for trains over level crossings. In addition, Oslo's and Bergen's tram or light rail systems have some level crossings. Most lines on Oslo metro ("T-banen") are free of them. Most of the level crossings were removed from the old suburban railways in the western parts of the city, when the lines were upgraded to metro standard, but some crossings are retained on the Holmenkollen Line.
Poland.
Poland's level crossings has a red and white pole with two lights. Most crossings have two barriers while others have a single barrier large enough to prevent vehicles from going around. Certain crossings have one light, others without lights but are equipped with gates. Crossings without gates have crossbucks and at some locations, a stop sign mounted below the lights.
For safety precautions, level crossing alarms continue to sound until the train has passed through. At other crossings with more than one track, the alarm will continue if there's more than one train approaching. Electrical advisory signs are also in place at crossings where overhead wires for electrificated tracks are present.
Portugal.
Portugal's level crossings have bells, but most do not have lights. Two alternating flashing lights accompany the barriers, which can be manual or automatic. They also have a sign saying "" (stop at the red light). When activated, the bells ring, the lights flash, the barriers come down and the bells continue to ring.
Romania.
Romanian level crossings usually consist of 2 red lights, and one white light that indicates the fact that there are no trains approaching and the BAT[Barrier based] or SAT[only lights based crossing] are working perfectly. The bells are either electronic or mechanical (electronic bells being some of the loudest in the world) and only newer level crossings have barriers. Older level crossings can be seen most of the time having the stem for the barrier, but not the actual barrier.
Russia.
Russia's level crossings have one of the loudest bells. Like U.S. level crossings, Russia has two red lights. It acts similarly to U.S. level crossings, but the barriers go slightly up for one second before going down.
Every level crossing with barriers is manned by a crossing keeper, who depending on the crossing type, may operate it, or if it is automatic, ensure its correct operation.
There are three common kinds of crossings in Russia:
Serbia.
There are around 2,790 level crossings in Serbia. These crossings have red triangles with a yellow or white inside and two red lights in the triangle. When a train trips the gate system, the bell and the lights are first activated, then after 10 to 15 seconds the barriers come down. The bell is usually silenced once the barrier is lowered. The crossing barriers are red and yellow, while the crossbucks are either the same colour as the barrier or the background triangle. Unlike neighbouring Croatia and Slovenia, where crossings secured only with lights are fairly common, in Serbia they tend to be the exception; full barrier crossings are also rare, and if these exist, they are still manually operated.
Slovenia.
In Slovenia, level crossings are similar to Swiss crossings, in that they have a normal warning sign triangle but with two red lights inside it. The crossings have half barriers (mainly) and alarms that sound when a train approaches.
Spain.
Spanish level crossings have two alternating red lights and sometimes a pedestrian light on the other side of the crossing. When activated, the lights flash, the bells ring and the barriers lower, as the crossing is usually automatic. More rarely, once the barriers have fully lowered, the sound changes. For some level crossings, when the barriers begin to go up, the square light stops flashing. More often, the level crossings in Spain, unlike all other level crossings, activate a long time before the train arrives.
Sweden.
In Sweden there are 8,500 level crossings, according to Trafikverket, the Swedish Transport Administration (formerly Banverket, Swedish Rail Administration). On public roads they have light signals with or without gates. On private roads there are level crossings without signals. Most accidents occur on crossings without gates. For many years there have been activities to reduce the number of accidents, usually by adding gates, or adding light signals if there were none. On the main lines many bridges have been built, and also anywhere a new road or new railway has been built. Still there are some level crossings left on the main lines. A train speed of 200 km/h is allowed in Sweden over level crossings, if there are gates and an obstacle detection unit. This unit detects cars on the track and prevents the gates from closing fully and stops the train. According to Trafikverket, in 15 years there has only been one serious collision between a car and a train on such a level crossing, when a car ran through the gates just in front of the train. Level crossings on electrified lines have a wide sign above the roadway at the barrier line saying "livsfarlig ledning" (dangerous conduit). Some also have a sign saying "se upp för tåg" (beware of trains).
Switzerland.
Most level crossings in Switzerland have two red lights on the bottom of a triangle backboard, bells, barriers, and more rarely, another triangle with one red light in the middle. When activated, each red light flashes for a third of a second. The bells ring as well. After a few seconds, the barriers come down and the bells stop ringing. Most Swiss crossings are automatic and a few are also on rack railway systems, so they have rising teeth that come out from the ground.
Turkey.
Turkish level crossings have two red lights, alarms, barriers and at most crossings, a large red light displaying "DUR" (stop) which remains lit until the trains have cleared the crossing. Crossings with triangle backboards similar to the ones in Serbia and Switzerland are used but over time, new modern and refurbished crossings that uses US style mechanisms are more common. These crossings have a white crossbuck with red lettering displaying Demıryolu Geçıdı (translated Railroad Crossing). In addition, a sign similar to the ones in Germany is used if the tracks is electrified with overhead wiring.
Ukraine.
Level crossings in Ukraine can consist of two red lights and possibly a white light to indicate the crossing is in working order. Barriers can also be included, as well as a vast array of noises that accompany the closure.
United Kingdom.
Level crossings in the United Kingdom started out as manually gated crossings opened by a signalman. These were standard all across the network until mechanised barriers started to be introduced. These could be operated by a signalman adjacent to the crossing or were automatic. After the major Hixon rail crash in 1968, the design of level crossings started to change, and all mechanised crossings had to have a preliminary amber light fitted, which makes UK level crossings one of only a few countries with this design of crossing. More recent advantages in technology have led to more technical automatic crossings, safer open crossings, and crossings with obstacle detection systems to detect stray people or vehicles on the crossing. Nevertheless, level crossings were the location of 54 collisions between trains and road vehicles between 2011 and 2018.
The nearly seven and a half thousand level crossings in the United Kingdom can be broadly classified into two types: protected crossings – consisting of warning lights and gates or barriers which prevent crossing when a train is nearby; and unprotected crossings – footpaths, bridleways and user-worked crossing (where the responsibility for ensuring a safe crossing lies on the user). Network Rail, responsible for maintaining most of the crossings, is taking steps to reduce safety risks, for example by closing crossings where possible. There are still old wooden manual gates in use at regular and Heritage railways.
Africa.
Algeria.
 Algerian level crossings have a single flashing light surrounded with a red frame. The crossing gates and lights are based on crossing equipment used in France. Since most crossing gates have half barriers, trains often blow the horn to deter drivers from going around the barriers.
Crossings that have electrified tracks have arches with signage reading " (Danger of Death) and " (High Voltage), warning drivers and pedestrians to not make contact with the wiring or drive through with oversized vehicles.
Angola.
Level crossings in Angola are the same as the variants used in Portugal, featuring a yellow sign with red text and the bells ring until after the crossing arms are raised.
Benin.
 Level Crossings in Benin have railroad bells and lights similar to crossing equipment used in France. However most of these crossings do not have gates and instead, the bells continue to ring until the train has passed.
Botswana.
Botswana uses crossing gates and lights that are based on variants used in Canada and the US. Each crossing uses Czech crossbucks and electronic bells.
Côte d'Ivoire.
Many level crossings in Côte d'Ivoire remain manually operated with only target boards and crossing guards to signal drivers. Plans to modernize the crossings with lights have been announced as of 2018.
Egypt.
Crossings in Egypt that have bells continue to ring for the duration of the gates being lowered. Some crossings around Cairo have multiple lights and alarms. Other level crossings that have been recently refurbished uses crossing equipment and bells that is utilized in Spain. At most locations, the gates can stay closed for a long while.
To cut down on crossing incidents, the newly installed crossing lights have a arrow indicator between the flashing lights to highlight the direction of any trains. Some crossings also have cameras mounted above the tracks which can lead to issuing fines for drivers that ignores safety rules such as going around the barriers.
Ghana.
Ghanaian railroad crossings uses gates, lights and crossbucks that are based on the designs of Dutch railroad crossings. Most crossings, however, do not have gates or lights.
Morocco.
In Morocco, many crossings have crossing gates, lights and bells based on the equipment used in France. Other locations have level crossing equipment based on crossings in Spain and Chile.
Nigeria.
A majority of level crossings in Nigeria are manually operated and others do not have gates. Crossing guards are present and signals drivers when trains are approaching.
Yellow crossbucks with black text is used around Nigeria. These crossbucks resembles the ones used in Australia and at some locations, others that are based on New Zealand.
Senegal.
Most level crossings in Senegal are unguarded. Crossings that have lights and bells are based on the french level crossings. Two variants of crossbucks are used, one that is the target board used by France and others have a red crossbuck with white dashes.
Some crossings that are manually operated uses modified stop signs that flash when trains are approaching.
South Africa.
Level crossings in South Africa usually consists of lights and a barrier though others remain unguarded. All crossings uses large crossbucks from Czechia that is used in neighboring countries as well.
Due to increased crossing fatalities and accidents over the years, many level crossings have since been replaced with bridges and underpasses.
Tunisia.
Crossings in Tunisia follow the same practices used in France, Morocco and Senegal. As such, warning crossing equipment is based on installations used by the French. However some differences exist as the target boards are black instead of gray and some crossings have a second bell that emits a louder sound when ringing. Other crossings have lights that are raised much higher.
Zimbabwe.
Crossings with lights in Zimbabwe are similar to New Zealand but with the crossbuck placed between the lights. Due to history of vandalism and decline of the economy, many crossing gates and lights remain out of order though as of 2018, plans were put into motion to modernize and refurbish the railroad infrastructure and signaling.
Zimbabwe crossbucks are like the crossbucks used in US but the sign is yellow instead of white and the center of the signage has the text moved to the corners of the road sign. Czech style crossbucks used in Botswana, Namibia and South Africa is also present at other locations.
North America.
Canada.
Public railway crossings in Canada are required by law to be marked by a crossbuck, along with alternating flashing red lights and gate arms on high-traffic roads. Crossbuck signs are white with a red outline and, if the situation warrants, contain a supplemental sign to indicate the number of tracks. Private roads in Canada that cross tracks are marked with either a crossbuck or a stop sign. A large number of public Canadian Pacific Railway level crossings in Ontario do not have a crossing arm but still utilize the crossbuck and alternating flashing lights. The advance-warning sign, which is a yellow diamond shape with a diagram of a track crossing a straight segment of road (similar to a crossroads sign, except that the horizontal road is replaced by a track). Before changes in regulations mandated bilingual (English and French) or wordless signs, either "railway crossing" or "" was written on each crossbuck. Lights, gates, and bells are identical to their American counterparts.
There are 22,884 public railroad crossings in Canada in 2018, according to the UNECE.
Mexico.
Mexico has also begun to install US-style crossing signals on some of its KCS de México, Ferromex, and Ferrosur rail lines; however, the majority of railroad crossings in Mexico remain unsignalled, marked only with a crossbuck. The crossing devices are very similar to the US models, sporting larger lights. The crossbucks read ", ", or "". The majority of crossings are solar-operated, and the lights flash faster than the US signals. Unfortunately, these devices are easy targets for vandals as they steal their components such as gate motors and solar panels. In many cases the gates do not lower due to vandalism or lack of maintenance. In some cases, due to the lack of maintenance, the lights do not turn on at all. The rail companies, which by law are required to maintain the crossing signals, take little to no action in maintaining these devices, and the majority remain unmaintained, posing a threat to drivers.
United States.
The first US patent for manual/electrical crossing gates was awarded on 27 August 1867, to J. Nason and J. F. Wilson, both of Boston.
There are 209,765 level crossings in the USA in 2018, according to the UNECE.
Crossing identification.
Every crossing, whether above grade, below grade, or at grade, is required to be assigned a unique identifier which is a six-digit number with a trailing letter used as a checksum. This identifier is called a Grade Crossing Number, and is usually posted with a sign or sticker on the sign or equipment. This allows the exact location of a crossing anywhere in the United States to be identified in the event of an incident involving that crossing.
Traffic control devices.
All public crossings in the United States are required to be marked by at least a crossbuck. But sometimes even that is not there. The 2009 Manual on Uniform Traffic Control Devices requires passive crossings (crossings without actuated flashing lights or gates) to have either stop signs or yield signs in addition to the crossbuck, unless a flagger will stop traffic every time a train approaches. Normally a yield sign is used, unless it is determined that all vehicles should stop at the crossing, such as a location with poor sight distance. All passive crossings must be upgraded to meet this standard by 31 December 2020.
If the crossing has more than one railroad track, the crossbuck is required to have a small sign beneath it denoting the number of tracks.
As traffic on the road crossing or the rail crossing increases, safety features are increased accordingly. More heavily trafficked crossings have "automatic warning devices" (AWDs), with alternately flashing red lights to warn automobile drivers and a bell to warn pedestrians. Additional safety is attained through crossing gates that block automobiles' approach to the tracks when activated. Increasingly, crossings are being fitted with four-quadrant gates to prevent circumventing the gates.
Operation of a typical AWD-equipped railroad crossing in the United States is as follows:
Some AWD track circuits are equipped with motion detectors that deactivate the crossing signal if the train stops or slows significantly before arriving at the crossing.
As indicated above, the pattern of the bells at each individual crossing can be different. (These bells should not be confused with the bells that are mounted on the trains.) Generally, the bells follow one of these patterns:
Some level crossings that are located close to intersections with traffic lights program the signals with a preemption sequence so when the approaching train trips the track circuit, it not only activates the crossing signals, but also changes the traffic lights facing the crossing to green, to clear any traffic that may be queued on the crossing. If the intersection's stop line is right before the tracks (typically sharing the crossing's stop line), the track circuits would change the traffic lights to red (often without a yellow phase). Some track circuits place the signals into flash mode the entire time the AWDs are active. In cases where railroads share the right of way with vehicular traffic, simple railroad preemption may cause an all-red flash in traffic lights.
A few level crossings still use wigwag signals, which were developed in the early 1900s by the Pacific Electric Railway interurban system in the Los Angeles region to protect its many level crossings. Though now considered to be antique, around 100 such signals are still in use, almost all on branch lines. By law, these signals must be replaced by the now-standard alternating red lights when they are retired. In 2020 there would be only 33 wigwags active. But they will remain on heritage lines and in amusement parks. 
United States Federal Railroad Administration regulations restrict trains to a maximum speed of at standard grade crossings. Crossings are permitted up to only if an "impenetrable barrier" is in place to block traffic when a train approaches. Crossings are prohibited at speeds in excess of .
A track that will run high-speed trains in excess of is being tested in Illinois between Chicago and St. Louis, Missouri. Here, due to the high speed of the trains, gates that totally prevent road traffic from reaching the tracks are mandatory on all level crossings. Steel mesh nets were tested on some crossings to further prevent collisions, but these were removed because of maintenance issues in 2001.
A new device, called "StopGate", has been installed at four locations — one in Madison, Wisconsin, another in Monroe, Wisconsin and two on a light rail system in Santa Clara, California. This system resembles a fortified version of a standard crossing gate, with two larger arms blocking the entire width of the roadway and locking into a securing device on the side of the road opposite the gate pivot mechanism. The gate arms are reinforced with high-strength steel cable, which helps the gate absorb the impact of a vehicle attempting to crash through the gate. The manufacturer claims that the StopGate can stop a truck within . The system worked as intended at the Madison crossing, when the system stopped a truck while a Wisconsin and Southern Railroad train was in the crossing. This experiment has ended due many defects. They are now normal level crossings again.
Another new type of barrier was tested in Michigan and was hoped to reduce the number of times drivers attempt to drive around lowered crossing gates. The new devices are called "delineators" consisting of a series of flexible bollards that rise vertically out of vertical tubes in the pavement when the crossing signal is activated. The delineators are designed so that they will not be broken and will not damage vehicles if they are hit, allowing vehicles to exit the level crossing if they are already within it when the gates are activated. The test period for the new barrier began on 5 December 2007, and ran for at least 17 months.
Locomotive equipment.
In the United States and in countries following United States practices, a locomotive must have a bright headlight and ditch lights (two lights located below the headlight but above the pilot), a working bell, and a whistle or horn that must be sounded four times (long-long-short-long), similar to the signal for the International Morse Code letter "Q", as the train approaches the crossing. Oscillating lights such as Mars Lights as well as strobe beacons have also been used in the past to increase train visibility at level crossings, but both have mostly been replaced by the simpler ditch lights. 
Quiet zones.
In the interest of noise abatement, some American cities have passed laws prohibiting the sounding of bells and whistles. In December 2003 the United States Federal Railroad Administration published regulations that would create areas where train horns could be silenced, provided that certain safety measures were put in place, such as concrete barriers preventing drivers from circumventing the gates or automatic whistles (also called wayside horns) mounted at the crossing. Implementation of the new "Quiet Zone" Final Rule was delayed repeatedly, but was finally implemented in the summer of 2005. Rail "Quiet Zone" crossings still require bells as part of the AWDs, in addition to the wayside horns.
Central America.
Costa Rica.
INCOFER has crossings with crossbucks as in the photo, with the words "Cuidado con el tren" (be careful of the train), as well as crossbucks without lettering, and a normal stop sign (alto). Since most crossings do not have automatic gates, the train has to blow the horn. Some crossings have warning lights.
Cuba.
Cuban crossings are identical to old USSR era crossings; they also feature a US-style crossbuck.
El Salvador.
If marked at all, the railroad crossing will have a sign marking it. This sign says, "Alto, Mire, Oiga" (Stop, Look, Listen). There are no gates.
Asia.
Cambodia.
Following ongoing infrastructure improvements and refurbishment, level crossings with flashing lights and alarms were introduced in 2015. Crossings that are manually operated have lights mounted on the barriers.
The newly installed crossings equipment which was firstly introduced in Phnom Penh have double barriers and alarms that continue to sound until the crossing gates are raised.
China.
Chinese crossings have two red lights and at most crossings, a white light that remains lit when the crossing is clear. Level crossings in China uses alarms rather than bells.
Speed up campaigns have largely eliminated many crossings on heavily used trunk main lines though some still do exist. Most at-grade crossings in China are for smaller industrial spur and access lines which may or may not have crossing gates.
Hong Kong.
Most of Hong Kong's railway network is either underground or on elevated viaducts, meaning that level crossings are rare. However, level crossings continue to exist on the MTR Light Rail network, and one such level crossing was the site of a level crossing accident in 1994.
Israel.
Israel generally follows United States practices, and much of the Israel Railways network employs American-made crossing warning equipment. The crossbucks used, however, are more similar to the Russian type.
India.
A majority of the level crossings in India are manually regulated. Signals and barriers are installed at all crossings while manual crossings are additionally required to have the hand red and green signal lamps. Indian Railways aims at elimination of all unmanned crossings and replacing them with manned crossings.
Indonesia.
Most level crossings in Indonesia have sirens. They also have two red lights (usually) and full barriers in red and white. Level crossings in Indonesia are not all officially operated by the Railway Company; some crossings (usually in rural or village areas) are guarded by civilian volunteers, and are not usually guarded 24 hours. Crossings in cities and urban areas are fully operated by the Railway Company. Usually each level crossing has a small guard room to control the traffic and barriers at the crossing. Official crossings are marked by sirens and red-white (Indonesian flag-like) barriers.
Level crossings in Indonesia tend to be congested by traffic, thus they are not automatic like in Western countries, so level crossing watchmen are usually posted at every crossing; these are employees from the Railway Company. However, plan to replace these crossings with automated and also with overpasses arose after the 2013 Bintaro Crash. The Ministry of Transportation bought 11 automated crossing barriers in 2015. 
At station Yogyakarta are still "rolling~gates" in use.
Prior to 2013, there were few major accidents in crossings. On 9 December 2013, a Commuter Line hit a Pertamina fuel truck stuck in Bintaro crossing (now replaced with a flyover), killing drivers ("masinis") and passengers in the front car. On 6 December 2015, a Metromini bus was hit by Commuter Line in front of Angke Station, killing 18 passengers of Metromini but doing no damage at all to the train passengers. On 6 April 2018 a Sancaka Train bound for Surabaya hit a container truck near , Ngawi, killing the train driver.
Due to the high death toll of train versus car accidents and severe traffic jam impact, local and national government have started to close level crossings, especially in Jakarta. Sometimes crossings are closed due to increase of headway, the like Jatinegara-Bekasi track that only leaves 3 from 7 unclosed posts. Numerous underpasses and flyovers have been created, and later the nearby roads are closed; for example, the replacement of 2013 crash site in Bintaro, South Jakarta with a flyover. Crossings in national highways are in the process of permanent closing due to high traffic; for example, the Klonengan crossing in Brebes, located in the main access to Purwokerto city.
Japan.
According to the Ministry of Land, Infrastructure, Transport and Tourism, there are in total about 33,300 in Japan as of 2016. These are easily identifiable with their yellow and black crossbucks mounted adjacent to the crossing, and newer crossings are often paved in green asphalt for easy recognition. Most of these are protected with usually equipped with alternating flashing red lights and yellow-and-black-striped barriers. Many signals are also equipped with signs with red LED arrows that indicate the direction of approaching trains.
Similarly to school buses in the United States, but unlike many other countries, all cars and bicycles must stop before proceeding over any level crossing in Japan, regardless of whether there are electronic signals, as required by the Road Traffic Act. The only exception is if the crossing is additionally controlled by a traffic light, called a ; in this case, if the light is green, it is not necessary to stop at the level crossing.
On some busy rail lines, especially in urban areas like in Tokyo, Osaka and Nagoya, so many trains pass through some level crossings that they are almost always closed to vehicular traffic. In some cases, such as the Chūō Main Line, more than 50 trains pass in an hour, which equates to only two minutes in which vehicles can cross the tracks during that interval, causing serious traffic congestion and inconvenience. Many such crossings, known in Japanese as , have been eliminated by grade separating rail lines, generally by moving them onto viaducts () or underground tracks ().
Malaysia.
Level crossings are largely manually operated, where the barriers are lowered using a manual switch when trains approach. A significant number of crossings are without barriers. Railway electrification in Malaysia has gradually eliminated level crossings in Peninsular Malaysia, replacing those along nearly all upgraded lines with large overhead viaducts or deep tunnels, and simply cutting off non-essential crossings outright. There are still many level crossings on the Johor Bahru-Gemas-Tumpat stretch, as well as on the line between Port Klang - Westport (Pulau Indah), as electrification has yet to be extended to these routes.
Myanmar (Burma).
Myanmar level crossings follows the practices of level crossings in Japan. Therefore, crossings gates and lights have the same characteristics and functions of Japanese crossings with indicators of which direction the trains are heading. Other crossings around Myanmar still remain manually operated but have warning lights and bells.
Pakistan.
Most level crossings in Pakistan features manually controlled swinging gates. Crossing keepers may allow emergency vehicles such as ambulances to pass through the closed gates during emergencies.
Recently, new crossing lights have been installed which flashes after the gates have been closed with some having a third light. Other crossings have recently installed lights similar to the ones used in China, featuring a non-flashing yellow light and two red lights. The red lights flash when the gates are closing. After closing, the lights stay lit until the train is cleared of the crossing, flashing again as the gates reopens. These lights also have a 2nd train sign that turns on if another train is approaching.
Saudi Arabia.
Saudi Arabia uses crossing gates with two red lights that remain lit when active. These gates are similar to the ones in the United States but also utilizes crossing arms and bells that are used in Germany. Yellow target boards featuring a US style crossbuck is used, as old red and white crossbucks is being phased out.
Singapore.
Singapore's Mass Rapid Transit (MRT) and Light Rail Transit (LRT) are built with no level crossings; most of the railway network are either underground or elevated.
The Keretapi Tanah Melayu (KTM) railway in Singapore had five level crossings: Gombak, Bukit Panjang, Stagmont Ring, Mandai and Kranji. All were manually operated by KTM railway staff. The crossings at Gombak Drive and Kranji Road featured gates, while the other three crossings utilized traffic lights with half-barriers. The level crossings were removed along with the railway tracks when KTM relocated from Tanjong Pagar railway station to Woodlands Train Checkpoint in 2011.
Sri Lanka.
Most level crossings in Sri Lanka have two lights that flashes slowly. Some crossings don't have lights but still has bells and gates. The bells continue to sound when the gates are lowered. New crossing lights have a third light that works similar to China and Pakistan; remaining lit when the crossing is clear.
Taiwan.
As most railways in Taiwan were built during Japanese administration, railway level crossings remain very common and generally built to the same design as Japan, though many urban crossings have been eliminated when the railroads have been moved underground, e.g. segments of the West Coast Line in Taipei City and Kaohsiung City, or moved elevated, or has converted to cubic crossing with road, or abolished, e.g. the former TRA Tamsui Line that is now the Taipei Metro Tamsui Line without any level crossings.
The Act Governing the Punishment of Violation of Road traffic Regulations () prescribes fines for drivers and pedestrians who commit certain classes of violations in regards to level crossings; these include disobeying flagmen, insisting to cross while a crossing's signals are active or when the gate is being lowered, crossing a passive crossing without stopping beforehand, and overtaking, making a U-turn, backing up, stopping or parking on a railway level crossing in a vehicle. Pedestrians can be fined 2,400 new Taiwan dollars for a violation, drivers of non-motorized vehicles such as bicycles can be fined between 1,200 and 2,400 dollars, and drivers of motor vehicles can be fined up to 15,000 to 90,000 new Taiwan dollars for a violation. If an accident occurs, the driver's license can also be revoked for a minimum of six years, and would face legal responsibility and compensation of damages.
Accidents at railway level crossings remain a very serious concern, such as an truck trespassing a level crossings and collusion with a Taroko Express in Jan 17, 2012. The Taiwan Railway Administration alone has hundreds of level crossings along its routes of slightly more than . In average, there is a level crossing each . An emergency button is installed on every level crossing in the country, allowing members of the public to report emergencies at a crossing to authorities, such as stalled vehicles or other obstacles.
Thailand.
Thailand crossings have two flashing lights that slowly flashes and are equipped with alarms. Each crossing that has gates has two yellow-orange strobe lights for better visibility when the gates are active. Most crossings have large flexible gates that fully blocks traffic from going around but other locations may use shorter gate arms. At many locations, the alarms continues to sound for the duration of the gates being closed but other crossings sound when the gates are closing and opening.
, the Thai rail network has 2,624 level crossings nationwide. Many have no crossing barriers, making them frequent sites of accidents. Some level crossings are manually operated, wherein the barriers are lowered using a manual switch when trains approach. There were/are still "roller-gates"in use, but these are increasingly being relaxed by heavy barriers. Sometimes they are still available as a reserve. Previously there were also where a cable came down the road, with red and white signs on it.
United Arab Emirates.
United Arab Emirates uses crossings that are much more similar to United States but like Saudi Arabia, these lights stays lit rather than flashing. UAE crossings have railroad crossing signs on black target boards.
Vietnam.
All railroad crossing signs in Vietnam use on base of Russian Federation crossing signs with white crossbuck and red border (St.Andrew crossbuck), cross each other at a 45-degree angle.
1.Devices and signaling arranged at horizontal lines
a) Guarded crossroads: barrier or shields, signal lights, electric bells, signboards, marker poles, fences, road markings on roads, railroad roadside signals (if any), and other signaling devices when permitted by competent authorities;
b) Automatic warning crossings: signal lights, electric bells, signboards, marker posts or fences, with or without automatic barrier, road markings on road, and other signaling devices when possible authorized level;
c) Roads across the signboards: signboards, marker posts or fences, road markings, and other signaling devices when so permitted by competent authorities.
2. Signal and equipment systems arranged at crossroads to ensure traffic safety and prevent accidents. All organizations and individuals must be responsible for protecting, not arbitrarily moving, appropriating, damaging or reducing the effectiveness and effect of the systems. 
in Vietnam are still "roller~barriers/gates" in use. Electric or manual. 
An extremely long level crossing is in Ho Chi Minh City, near Ga Go Vap station. The track crosses about twelve carriageways. There are 8 barriers and 2 very long roller-barriers/gates. They have to be pushed.
Oceania.
Australia.
Australian railways generally follow United States practices, and they have increasingly been employing American-made crossing warning equipment, such as level crossing predictors, which are able to provide a consistent amount of warning time for trains of widely varying speeds. There are many different types of rail crossings in Australia; railways that run through rural areas often do not have barriers or even lights/bells to warn of incoming trains, while urban crossings will either have lights and bells or lights, bells, and boom gates.
In Melbourne, there are several level crossings where electrified train tracks cross roads with electrified tram tracks. These crossings are fitted with equipment to change the voltage supplied to the overhead wiring depending on the vehicle using the crossing at that point in time, and trains are severely speed-limited across these intersections. Due partly to this complication, as well as recent deaths, accidents and traffic problems at level crossings, the Victorian Government is removing 50 of Melbourne's most dangerous and congested level crossings. The 50 removals are due to complete by 2022, with a further pledge from Premier Daniel Andrews to remove an additional 25 if re-elected at the 2018 state election.
All cases where a train line crosses a road are classified as level crossings whether or not they are signed. A tram track in its own right-of-way crossing a road can also be classified as a level crossing if it is signed with a crossbuck reading either "TRAM WAY CROSSING" or "RAIL WAY CROSSING". Otherwise, it is considered a regular intersection and usually has either traffic lights or a give way sign facing the road (see Gallery).
Some recent innovations in Australia are to provide crossbucks with a pair of flashing yellow lights at about before the level crossing, called Advance Active Warning Signals (AAWS). This is done particularly where there are curves and other visibility problems on the road. AAWS are used where road speeds are high, and braking distances are extended, or where the level crossing is obscured by blind curves or sunlight. Another innovation is to transmit level crossing warning signals by radio into the cabin of nearby vehicles. This would be particularly useful at passive crossings, which are not yet fitted with flashing lights.
In areas subject to the Advanced Train Management System (ETMS), level crossings are controlled by satellite down links, and supervised by satellite up links. 
Australia also has about 4000 km. to sugar cane narrow gauge railroads. Many level crossings on these lines are protected with the regular red railroad warning lights and crossbucks, often supplemented by a red flashing light on top of the pole.
New Zealand.
There were (in 2012) 1390 public road level crossings in New Zealand, of which 275 crossings are protected by flashing red lights, bells, and half-arm barriers; and 421 are protected by flashing red lights and bells only. The remainder are controlled by "Stop and Give Way" signs. Level crossings are the responsibility of rail infrastructure owner KiwiRail Network, the NZ Transport Agency, and if the crossing is on a local road, the local city or district council.
On the Taieri Gorge Railway in rural South Island, New Zealand, roads and railways share the same bridge when crossing a river, with the rail line in the road. Motorists, as well as giving way to oncoming traffic if required (the bridges have one lane) must ensure that the bridge is clear of a train, end to end, before starting to cross the bridge. For safety, trains are limited to while crossing the bridges.
In many parts of New Zealand, railway lines run parallel to and close (within ) to roads. Many level crossing accidents have been caused by drivers turning right into side roads crossing the railway line concentrating on finding a suitable gap in oncoming traffic so that they fail to check the railway line or notice the activated level crossing alarms until it is too late to stop. An accident of this type occurred in August 1993 at Rolleston, near Christchurch, when a cement mixer truck turned right off State Highway 1 and collided with the side of a southbound Southerner passenger train, ripping open two carriages. The accident resulted in three deaths, including the sister of New Zealand international cricketer Chris Cairns.
In 2020, KiwiRail changed the rate of flashing lights at level crossings from 85 fpm (flashes per minute) to the standard laid down by the "American Railway Engineering and Maintenance-of-Way Association" of 50 fpm so that a new order for level crossing equipment did not have non-standard requirements.
Major accidents.
Level crossings present a significant risk of collisions between trains and road vehicles. This list is not a definitive list of the world's worst accidents and the events listed are limited to those where a separate article describes the event in question.
Runway crossings.
Aircraft runways sometimes cross roads or rail lines, and require signaling to avoid collisions.
Gibraltar.
Winston Churchill Avenue intersects the runway of Gibraltar International Airport at surface level; movable barricades close when aircraft land or take off.
New Zealand.
A level crossing near Gisborne, sees the Palmerston North - Gisborne Line cross one of Gisborne Airport's runways. Aircraft landing on sealed 1310-metre runway 14L/32R are signalled with two red flashing lights on either side of the runway and a horizontal bar of flashing red lights to indicate the runway south of the railway line is closed, and may only land on the section of the runway north of the railway line. When the full length of the runway is open, a vertical bar of green lights signal to the aircraft, with regular rail signals on either side of the runway indicating trains to stop.
Sweden.
The Visby Lärbro Line between Visby and Lärbro crossed the runway of Visby Airport between 1956 and 1960.
