Sergei Sobyanin: Passengers take > 75 million D4 rides over the year

Exactly one year ago, the authorities launched the fourth Moscow Central Diameter (Kaluzhsko-Nizhegorodsky, D4), its passengers having taken more than 75 million rides to date, as announced by Sergei Sobyanin on his Telegram channel.

D4 is the longest, 86-kilometer diameter running throughout the capital and connecting Aprelevka and the Zheleznodorozhny microdistrict of Balashikha in the Moscow region,” the Moscow Mayor writes.

25 of its stations (about 70 per cent) are turned into in-city commuter terminals.

D4 is served by advanced trains, such as Ivolga 4.0 that were launched in May, the fleet, including on suburban routes, to be 100% updated by the end of 2025.
