Front metro car mod. 81-7036


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 carry passengers in the subway with a track of 1520 mm. 
The use of induction motors makes it possible to save up to 30% of the consumed electricity. The minimum number of contacts used in the power circuit helps to reduce the cost of operation and maintenance of engines.
