The Tatra K1 was an experimental tramcar developed by ČKD Tatra between 1964 and 1965. Previous Tatra units had been concerned primarily with gaining maximum capacity in a single tramcar, and Tatra sought to correct this through the development of its first articulated tramcar, the result being the K1. The K1 was based largely on the already established T3, although certain aspects of the electrical equipment were adjusted in the K1. After a short spell on trial in Prague, the two prototype vehicles entered service in Ostrava, where they remained for 3 years until 1968 before being returned to the manufacturer. The test runs had exposed problems with the electronic equipment of the K1, and thus the two prototypes remained the only ones ever produced.
