Passenger transport

Tram with increased autonomous course

Tram wagon 71-405-11 - joint development of "Uraltransmarsh" JSC and "ASK" CJSC

Trams with the increased autonomous movement are convenient for the organization of transport bundle between two cities, as well as for big cities. Lithium-ion accumulators in a design of such wagon reduce energy consumption up to 60% and allow to overcome separate sites of the route without a contact wire. The tram can pass from 100 to 150 km without additional charge. Charging takes 10-15 minutes, time of a total accumulators charge – 2 hours. The term of operation – 15-20 years.
