The T3 is a type of Czech tramcar produced by ČKD Tatra. A late-2000s study conducted on the Prague tram system has shown 98.9% reliability, the best of the Prague tram system fleet. During its period of production between 1960 and 1999, 13,991 powered units and 122 unpowered trailers were sold worldwide.
It became the most dominant tramcar model in Eastern Bloc countries, except for Poland, where locally produced trams from Konstal factory are still the mainstay in tram systems there, and Hungary, where ČKD only made inroads to the country's tram market during the late 1970s. Together with Soviet KTM-5 it is among the most produced trams, as of 2022, it is still the most widespread tram car in the world.
