The design would be applied in the 71-911, developed by PC Transport Systems on the basis of the bogie for the 71-625, which the former director of the trading house, Felix Vinokur had joined.

[11] The tramcar has air conditioning, thermal curtains for doors, mood lighting,[2] WiFi, individually heated seats, anti-corrosion lining on the side and USB charging sockets.

Without an adequate vehicle, Sinara tried to engage with Uraltransmash (which had its own low-floor tram model 71-415), but were unable to reach an agreement.

The contract had only fixed the total number of vehicles, but not the actual type, so Sinara was able to negotiate with UKVZ to build the trams.

[15] The trams are the 71-628M variant, which will feature a different exterior, have wheel lubricators and autonomous running for at least 1 km, although the delivery date has then been changed to 'by the end of next year'.

[23] The number of 71-628 trams to be purchased has to be finalised due to the need to eliminate defects,[24] but the test vehicle, in a long-standing tradition of operating the first vehicle of each type produced by UKVZ, will be sold to the city after issues are resolved and the car is painted in the city's livery,[25] although other sources say that it may only return if an order is placed for the same model.
