The Vityaz-M tram-car is an upgraded version of the Vityaz 71-931 tram-car that has already approved of itself. The Vityaz-M is the most popular model in the tram-car range manufactured by PC Transport Systems, which consolidated all the best of what we have developed and implemented since the company's establishment.  The tram-car is based on the unique low-floor elastic bogie of own development and manufacture. The modular railcar manufacturing principle, with the driver's separate compartment and the rear platform, allows for easy modification of the design. The railcar can be built both in a classical and  shuttle version, with two driver's compartments and bilateral location of the doors, for operation in routes without reversal rings.  Three- and multi-section railcars can be manufactured. In 2019, the modified version of the 71-931 М tram-car was manufactured: the tram mask  underwent a number of changes, and the driver's compartment became more functional and ergonomic.  The Vityaz-M is a new-generation modern, energy efficient, environment-friendly and elegant urban tram-car.
