Only new carriages of the 81-760/761 range are currently operating on the Serpukhovsko-Timiryazevskaya metro line. Ninety two eight-carriage trains have been transferred to the Varshavskoye and Vladykino electric engine houses serving the Serpukhovsko-Timiryazevskaya line since 2012.
“Renovation of the Moscow metro rolling stock is being carried out at an unprecedented rate. Today, six out of twelve metro lines are already equipped with new generation carriages.”Dmitry Pegov, head of the Moscow metro, said.
New generation carriages have been manufactured by the Metrovagonmash factory since 2010. They are safe and cost-effective to operate. Thanks to a recovery system, part of the used electric power returns to the mains when a train brakes. This allows the system to save up to 35 per cent of electricity. A modern asynchronous traction driving unit shortens train acceleration time to 80 km per hour from 40 to 27 seconds.
Carriage rolling stock renovation on the Serpukhovsko-Timiryazevskaya line lasted for a little over two years. The trains are supplied with modern fault detection systems that allow the driver to control the functioning of all the systems in each of the eight train carriages while remaining seated.
