Intermediate metro car mod.81-7037


The use of the axle box heating control system will improve driving safety and reduce the time spent on running gear diagnostics. The use of a system without braking will increase the service life of wheelsets. A subway car with an asynchronous traction drive is designed to transport passengers in the subway with a track of 1520 mm.
