71-931M “Vityaz-M” is an articulated three-section six-axle tram car with a completely low floor level, created by PC Transport Systems LLC at the facilities of the Tver Carriage Plant and the Nevsky Electric Transport Plant (St. Petersburg).
The first Vityaz tram was assembled in 2014 and at the end of October of the same year was presented at an exhibition in Moscow. After the exhibition, the tram was sent for testing on city lines. After completion of the tests, at the beginning of February 2015, “Vityaz” received a certificate of admission to mass production.
In June 2016, PC Transport Systems released the first Vityaz-M tram, which differs from the first model in the new shape of the front and tail sections and the layout of seats in the cabin. The Vityaz-M tram was first demonstrated at the Innoprom exhibition in Yekaterinburg. After the exhibition, Vityaz-M was tested in Volgograd.
In April 2020, PC Transport Systems began production of Russia’s first aluminum tram body based on the three-section Vityaz M model. Production is carried out at our own site in Tver – the Tver Mechanical Electric Transport Plant.
On November 11, 2019, Moscow Mayor Sergei Sobyanin and President of Transmashholding JSC Andrei Bokarev signed an agreement on the production of Vityaz-Moscow trams in the capital. The planned production capacity is at least 100 cars per year.
Thanks to Vityaz-M, PC Transport Systems LLC set two records (Russian Book of Records and European Book of Records): for the speed of production of trams (one car in 5 days for St. Petersburg) and for the volume of their delivery to Moscow (300 cars for Moscow for 2 years 6 months and 6 days).
In September 2017, PC Transport Systems, in association with Metrovagonmash, won a tender for the supply of 300 71-931M cars to Moscow during 2017-2019. The cost of the contract was 56 billion rubles. During the implementation of the contract in the fall of 2019, the parties signed an additional agreement for the supply of another 90 trams of the specified model by the end of 2020.
The Vityaz-M tram represents a new line of low-floor three-section trams developed by PC Transport Systems LLC and intended for urban passenger transportation on 1524 mm gauge lines. The production of trams 71-931M “Vityaz M” is carried out at the production sites of PC Transport Systems in Tver and St. Petersburg. At the Tver Mechanical Electric Transport Plant, welding and painting of the body, installation of floors and glass, as well as the production of low-floor trolleys are carried out. At the Nevsky Electric Transport Plant, final assembly is carried out – engines, seats and other interior elements, cabin equipment, and the installation of trolleys is also carried out.
The Vityaz-M tram has a separate modification, Vityaz-Moscow, intended for use in Moscow. As of May 2020, 350 Vityaz-Moscow trams operate in Moscow. In 2020, Moscow authorities entered into an additional contract for the supply of 50 Vityaz-Moscow trams.
All Vityaz-M trams use modernized bogies. The main directions of modernization of trolleys are improving the smoothness of operation and localizing production. To improve the smoothness of the ride, cone-lagers were developed and implemented and the suspension system of the fixed bogie was redesigned.
