The line was opened along with the Metro in 1984 with the original eight station segment, and crosses the city on a northeast–southwest axis.

Currently it comprises 15 stations and 19.1 km (11.9 mi) of track.

The line is served by the Moskovskoe depot (№ 1), and currently has 21 five carriage 81-717/714 and the modernised 81-717.5M/714.5M trains assigned to it.

A 5.2 km extension has been constructed to the southwest of the city and contains three stations: Hrushawka, Mikhalova, and Pyatrowshchyna.

The last extension was on 3 June 2014, when Malinawka was opened.
