Moldovan Railways came into being as an administration in its own right on the dissolution of the Soviet Union. The network is built to the Russian standard gauge of 1520mm. There are international connections with Romania (break of gauge) and Ukraine.
Several rail lines run through the breakaway region, including the main line from the Moldovan capital Chisinau to the Ukrainian border, via the Transdniestran capital Tiraspol. Services on these lines are operated by Moldovan Railways.
