newest retro-stile tram "Dovlatov" (model 71-421R) developed specially for St Petersburg by Uraltransmash
two-section articulated streetcar model 71-421R "Dovlatov" was developed specially for St. Petersburg at Uraltransmash of Rostec State Corporation. Uraltransmash is a subsidiary of Uralvagonzavod, one of the leading companies in the field of locomotive and railcar construction in Russia. The enterprise is known primarily for its military products - artillery systems, the production of streetcars is part of the conversion program. Two versions of streetcars are produced, which are named after famous Russian and Soviet writers: three-section model 71-431R "Dostoevsky" and two-section model 71-421R - "Dovlatov". They operate on route No. 6, which runs through the center of St. Petersburg. A total of 76 units of retro streetcars were ordered - 42 model 71-431R "Dostoevsky" and 34 cars of model 71-421R "Dovlatov". The design of the new streetcars echoes the famous Leningrad streetcar LM-57 informally named "Stilyaga" (the mod) but uses the most advanced technologies. In particular, it integrates an active safety system that can independently perform braking, as well as a system for monitoring the driver's condition.
For a long time the progress in city tram design was retarded by the absency of low-level bogie. Old Soviet bogie model can not allowed to develop really modern low-floor tram models. Old type can be seen see here www.flickr.com/photos/cetus13/50020591482/in/album-721577...
At early 2000s the one of the leaders in streetcar production in the USSR and Russia, The Ust-Katav Wagon-Building Plant named after S. M. Kirov (Ust-Katavskiy Carriage Works, UKCW; Усть-Катавский вагоностроительный завод имени С. М. Кирова) located in Ust-Katav, Chelyabinsk Oblast, Russia started to develop modern model of city tram with all low-level floor that needed design of new special bogies. But the innovation tram of the model 71-625 has never been produced. After the design of the new tramway bogie was completed, the UKCW unexpectedly broke off relations with its Trading house that had sponsored the development. In 2013 the chief engineer of UKCP moved to a new company founded by Felix Vinokur which bought the rights for the bogie after his leaving the founders of the Trading house Ust-Katav Wagon-Building Plant LLC. Thus, a new tram manufacturer appeared in Russia, The PC Transport Systems LLC. Example of their bogie see here www.flickr.com/photos/cetus13/52962023548/in/album-721577...
It seems that another type of modern bogie was redeveloped by Ust-Katavskiy Carriage Works or even Uraltransmash (?) that utilise simplified Chevron rubber primary suspension instead of helical spring and swing arm.
