In the previous programme the radial lines, with an ever-increasing build-up of passengers, were forced to use the central transfer points and those on the ring, severely overcrowding the system.

However, after several debates, this was altered and the line would continue westwards until it reached Volzhsky Boulevard and only then turn southwards towards the districts of Lyublino.

This station was left incomplete due to nearby factories heating up the soil, which prevented the freezing of the underground water to allow the construction of an escalator tunnel.

The development of further extensions was for many years delayed and paralyzed by the lack of finances, and only in 2005 construction was resumed on the long-awaited second stage towards the city centre, with Trubnaya being the first to open on August 30, 2007.

The second segment of a central extension was opened on June 19, 2010 (construction was resumed only in early 2007) and included two stations Dostoyevskaya and Maryina Roshcha.

The extension of the line from Maryina Roshcha northwest to Petrovsko-Razumovskaya via Butyrskaya and Fonvizinskaya was originally planned to be opened in December 2015.

According to the targeted investment program of Moscow from 2022 to 2023, 7 billion rubles will be allocated for the construction of the station with the working name Yuzhny Port.
