The 1524mm-gauge vehicles were designed by PK Transportnye Sistemy, Russia, and built locally by Transmashholding (TMH) subsidiary Tver Carriage Works (TVZ).

Tver is the first customer for the type 71-911, which has been developed specifically for Russian operating conditions with a patented suspension system to ensure high ride quality even on poor track.

The 16.4m-long single-section vehicles for Tver are 2.5m wide and accommodate up to 180 passengers, 33 of them seated.

Last year one of the vehicles underwent a two-month trial on Moscow's tram network.
