The first prototype of T1, T1 TW 5001, which today is considered the forefather of all Tatra trams, premiered in the streets of Prague on 22 January 1951. It is now on exhibition in the Prague Museum Depot (Muzeum Vozovna Střešovice) in Střešovice. The cars remained in use into the 1960s, when they were converted into T3-type vehicles. The last T1 was retired on 4 April 1987, in Plzeň.
