Russian President Vladimir Putin and Moscow Mayor Sergei Sobyanin opened four stations of the Troitskaya Line: Akademicheskaya, Vavilovskaya, Krymskaya and ZIL. The train traffic here will be controlled by the digital automation system of Natsproektstroy Companies.
ZIL Station has been equipped with the fastest MPC-SM computer-based interlocking system in Russia and the CIS to control point switches and signals: it takes only 0.45 seconds to complete a data exchange cycle with all devices. This will make the operation of the final point of the radius, where the trains will turn around, as efficient as possible.
MPC-SM is a proprietary system of Natsproektstroy Companies, independent of imported components. Thanks to the modular architecture, additional wayside equipment can be quickly connected to it. In the future, this will facilitate the integration of ZIL Station with the station of the same name on Biryulevskaya Line under construction.
NPS specialists have installed modern power supply systems and monitoring modules for track circuits throughout the new section.
The automation equipment is protected from dust, moisture and voltage fluctuations. Components have hot sparing; data transmission channels are redundant. The system features the strongest cyber protection. All this guarantees reliable and efficient operation of the equipment.
The intervals between subway trains are shorter than on the railway, and passenger traffic is more intense. With such a busy line, digitalization provides high transportation safety.
The Troitskaya Line will become one of the longest radii of the Moscow Subway and the largest beyond MKAD. The length of the line will be more than 43 km, it will run from ZIL Station to the New Moscow.
