In the 1970s and 1980s, 112 T2 trams were modernized into T2R. Modernization included overhauling of electrical equipment (similar to
Tatra T3) and some changes in the car body. That modernization helped the trams to survive into the 1990s. Two T2Rs were modernized in the early 2000s in
Liberec and these two remained in everyday use till 2018. These trams have been bought by Prague and after reconstruction are in daily use on the retro line 23. In Brno, Liberec and Ostrava four other T2Rs are used as service trams. == Production ==
