Longest train services

This article lists longest passenger rail services that are currently scheduled and running directly between two cities. This list is not complete due to the complexity of various railway systems, their timetables and difference in schedule administration between countries. To keep the list simple, only services that are point-to-point direct between two cities are listed. Services that require railcar exchanges, coach changes, shunting or station transfers are not listed.

Europe.
Due to widespread availability of affordable air travel, train services in Europe are limited to distances that can be covered in a single day or a single night, with very few exceptions. Especially the German and French operators have discontinued their sleeper services. This includes all sleeper connections to Copenhagen, making it impossible to travel by train Oslo–Brussels without an intermediate hotel night or using seated trains with long nightly changes.
The longest daytime journeys are taken by the Hamburg to Budapest service.
Services to and from Russia and Ukraine (traditionally targeted at poorer demographics) resisted longer, but these, too, have been reduced and reinvented in recent years. As of 2015, there are 3 services connecting Moscow with Western Europe, which are by far the longest ones on the European continent. These now feature luxurious sleeper cars and are targeted primarily at wealthier customers, with ticket prices well exceeding air fare. Most services connecting Kyiv with Western Europe have been discontinued all together (due to the poor Ukrainian railway infrastructure being a significant contributing factor), with one lasting daily train to Budapest, taking more than 24 hours to complete its journey.

Longest high-speed rail service.
The China Railway G403/4, G405/6 and D939/40 Beijing-Kunming high-speed train (2653 km, 10 hours 43 minutes to 14 hours 54 minutes), which began service on January 1, 2017, is the longest high-speed rail service in the world.
The previous record-holder was the likewise Chinese Beijing–Guangzhou–Shenzhen–Hong Kong high-speed railway at 2230 km.
Eurostar previously held the record for its London to Cannes route, which set a record of 1421 km non-stop high-speed service in 2006 (prior to the opening of High Speed One) – this was however not a regularly scheduled service. Currently, the record holders outside China are the Thalys service from Amsterdam to Marseilles, at 1265 km in 7 hrs, 15 mins, and the Eurostar from London to Marseilles, at 1215 km in 6 hrs, 26 mins.
