“Work has been completed on the installation of a modern smoke exhaust system at the reconstructed Varshavskaya station of the Big Circle Line of the Moscow Metro”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.

Mosinzhproekt Group of Companies is a general designer and general contractor to build new lines and stations of the Moscow Metro.

“Special columns with fans have been installed on the platform, which will extract smoke from the station through sub-platform channels in case of emergency”, said Andrey Bochkarev.

The head of the Construction Complex added that as part of the reconstruction, work was also completed on the traction step-down substation (TSS) to supply power to the entire station complex.

Yuri Kravtsov, General Director of Mosinzhproekt JSC, specified that, in addition, work on upgrading the utilities at Varshavskaya is being completed.

The final stage includes the renovation of the automation and telemechanics for train running, as well as the general ventilation system.

The Kashirskaya and Varshavskaya stations of the former Kakhovskaya Line are being reconstructed to integrate them into the BCL. Kakhovskaya has been operating as part of the Big Circle Line since 2021.

Its complete reconstruction, in fact, new construction, integration into the BCL is underway”, said Sergei Sobyanin.
