The Moscow Metro continues its planned modernization of its track infrastructure. New lines and upgraded sections are increasingly using continuous welded rails—so-called "velvet tracks"—which provide increased comfort and reliability for trains.
Today, the metro already has almost 400 km of continuous track. New lines are being built with long tracks, while existing lines are gradually replacing the connecting tracks as part of an infrastructure upgrade program.
The main advantages of continuous welded rail tracks for passengers are:
Increased travel comfort: trains run smoother and are virtually silent; increased safety and reliability: the absence of joints reduces rail wear and increases the stability of the track structure; increased speed due to improved track conditions.
A key role in the creation of continuous track is played by aluminothermic welding technology, which allows rails to be joined into a single continuous structure.
In 2024, four new stations on the Troitskaya metro line opened. Nearly 20 kilometers of continuous welded track were laid in both directions on this section. Overall, over 50 kilometers of continuous welded rails and 160,000 reinforced concrete half-ties were used on the existing section of the line from Novomoskovskaya to ZIL, along with hundreds of kilometers of cable lines for train control systems.
"To make trains run even smoother and quieter, we're modernizing the existing infrastructure. We're installing continuous welded rails on all new and many existing metro lines. We continue to make passenger travel more comfortable and safe, as instructed by Moscow Mayor Sergei Sobyanin," said Maxim Liksutov, Deputy Mayor for Transport and Industry.
Comprehensive infrastructure modernization—updating rails, developing automation and telemetry systems, and upgrading rolling stock—has resulted in one of the best performance indicators in Europe: the average speed of trains on the Moscow metro, including stops, is 41 km/h, with a maximum permitted speed of up to 80 km/h.
The leaders in average travel speed were the Kalininskaya, Nekrasovskaya and Troitskaya lines.
The development of continuous welded rail tracks is part of the capital's transportation development strategy through 2030. This strategy includes completing the Troitskaya Line, opening the Rublevo-Arkhangelskaya and Biryulevskaya Lines, and commissioning new electric train depots.
