The Tatra K2 is a Czech articulated tramcar that was produced by ČKD Tatra from 1966 to 1983. It was the company’s first production articulated tramcar, developed after the experimental prototypes K1 failed to enter production due to issues with the new electrical system. The Tatra K2 was produced in various versions, including the K2SU and K2YU. One of the locations where the Tatra K2S can be found is Bratislava, Slovakia.
