The Twist is currently operated in Częstochowa, Metropolis GZM, Kyiv, Kraków, Wrocław, Craiova and Tallinn.

The Tramicus model was built until 2008, and in 2010 the production of wagons from the Swing family began.

[2] Their constructions were similar – the tram with a length of about 30 m had 5 sections and moved on 3 rigid trolleys.

In the same year MPK Częstochowa [pl] announced a tender for the purchase of brand new low-floor trams, because due to the planned opening of a new tram line, the needs of rolling stock increased.

Another requirement of the customer was all swivel bogies with a classic axial wheelset.
