Trams in Pyongyang

Pyongyang Tram is a public tram system in Pyongyang, the capital of the Democratic People's Republic of Korea (North Korea). The first line of the current system opened in 1989. There are currently four lines in operation.
Overview.
Before the Korean War from 1950 to 1953, there were three tramway systems in the entire Korean Peninsula: one each in Seoul, Busan and Pyongyang. However, the system in Pyongyang was discontinued after the war, largely due to the significant destruction of the city by US/UN bombing attacks. The remaining two in Seoul and Busan survived the war but were eventually discontinued too when motorcars became more common and a larger means of transport in South Korea in 1968, thus leaving no tramway networks on the peninsula.
During the period of the Arduous March, the service of tram lines became sparse, and often trams would not run due to the lack of drivers and shortage of electricity.
Unlike South Korea, personal ownership of automobiles in North Korea is very rare. North Koreans, especially those living in Pyongyang and other major cities, rely mainly on government-run public transport. In Pyongyang, there are trolleybuses (the Pyongyang trolleybus system) and subways (the Pyongyang Metro), with these two serving as its main forms of public transport. However, as trolleybus lines became gradually overcrowded, the city decided to re-open tram-lines. The first line was built and opened in 1989.
A number of Tatra T4 trams and its trailer B4 were bought from Dresden, Magdeburg and Leipzig in 1997-1998.
In 2003, however, the section of Line 1 between P'yŏngyang-yŏk and Songyo was closed, as the bridge over Taedong River started to deteriorate, splitting Line 1 into two parts divided by the Taedong River. The section from Songyo to Songsin was eventually replaced by a trolleybus in 2014. The part crossing the bridge was replaced by a bus service.
In 2008, the City Transportation Company of Prague sold 20 used T3s to Pyongyang Public Transportation Enterprise together with a shipment of tram-rails. These trams were made in the late 1970s and the early 1980s. According to Ondřej Pečený, a spokesman for the City Transportation Company of Prague, these trams are in very good condition, and can run for at least two years without the need of a service. 
The tram cars were made by Tatra, a Czechoslovak company, during that nation's socialist era. Various types are used, but there are currently no low-floor tram cars.
Foreign tourists were previously not permitted to ride the tram lines, but some recent tours have started to include tramway rides (though rides are not shared with locals and are instead chartered, unlike the Pyongyang Metro).
Due to the need for transport, tram drivers cannot afford to relax, even on holidays.
Lines.
There are currently three lines in operation plus a meter gauge line operated by the military.
As of 2006, the fare is ₩5 for any section. There are also coupon tickets (; "sinae ch'ap'yo") issued in the form of tickets inserted into the fare box.
Rolling stock.
Prior to 2018, the rolling stock used were the Czechoslovakian ČKD Praha Tatra T6B5K, Tatra T3/SUCS, Tatra T4D and B4D and KT8D5K in either red/white livery or blue/white. The Kŭmsusan line uses VBZ Be 4/4 Type Ib rolling stock on a different gauge of 1,000 mm, rather than 1,435 mm for lines 1-3. The Shenyang ST4 had been retired in 1999 due to their failing articulation joint and subsequently converted into Chollima-961/971 trolleybuses while it is possible others were sent to the Chongjin tram system where they received a new body at the Chongjin Bus Factory.

In August 2018, following the introduction of new trolleybuses and metro cars, new partially domestically-produced tram cars were introduced in Pyongyang for the first time in about twenty years. The bodies were manufactured by Pyongyang's Bus Repair Factory and named Tongil, on the chassis of the Tatra KT8D5K.
