In 1937 the North Caucasus Railway was renamed after the Soviet party leader Sergo Ordzhonikidze but soon reverted to its traditional name. It was in the late 1950s that most of the railway network was electrified.
In 1987 the line from Zverevo north to Chertkovo was transferred from the South Eastern Railway to the North Caucasus Railway, with the new connection between the two railways being just north of Chertkovo railway station.
