The first and only railway in Nagorno-Karabakh opened in 1944 between the regional capital, Stepanakert, and Yevlax in Azerbaijan, when both were in the Azerbaijan Republic of the Soviet Union. It was built to Russian standard gauge of 1520mm.
On the dissolution of the Soviet Union in 1991 Nagorno-Karabakh declared its independence from Azerbaijan. This was not recognized by Azerbaijan and conflict, in which Nagorno-Karabakh was assisted by Armenia, ensued. Armenian troops still occupy Nagorno-Karabakh and neighbouring parts of Azerbaijan. The railway was badly damaged in the conflict and there is no prospect of reopening until the political situation is resolved.
