The articulated railcar Tatra K2 is the successor to the Tatra K1 . It was manufactured by ČKD Tatra between 1966–1983.
Development history
K2
After the experiences with the Tatra K1 , it was decided to install the electrical equipment of the already proven type T3 . The number of driving and braking levels was increased, and the middle bogie received a mechanical brake. The acceleration was slightly lower compared to the T3. The electrical control UA 12 was taken over from T3 (TR 37) with minor changes. In 1966 the prototype with the number 7001 was used for test drives in Prague . This car was then exposed at MSV ( International Engineering Fair ) with the number 7000 in 1966. After MSV it was tested in Most (German Brüx ) until 1967 and in 1968 it was sold by the manufacturer to Brno . Here the prototype initially drove with the number 607, but in 1969 the number was changed to 1007. In 1989 this car with all the oldest K2s from 1967 (1002-1006; car number 1001 burned down in 1988) and 1969 (1008-1022) was discarded. Then it was scrapped.
After successful testing, series production began in 1966 . K2s are still running in Czech and Slovak cities today, some of them still in their original state, some of them extensively modernized.
K2SU
The series production of the vehicles delivered to the Soviet Union took place from 1967 to 1970. The short production time is due to the fact that articulated vehicles were still the exception in the Soviet companies at that time and therefore represented a special technical feature. One vehicle has been preserved in Yekaterinburg , which was reconditioned as a historic vehicle with the number 801.
K2YU
The Sarajevo tram was the only company in Yugoslavia to receive this version . The only difference to the K2 is that the K2YU had the pantograph above the rear bogie. It also had the small, narrow line displays like the T3D. A total of 90 cars were delivered between 1973 and 1983 and were given road numbers 201 to 290.
Conversion to K3R-N / SATRA III
After the turn of the millennium, modernized K2 units in Brno and Sarajevo were expanded with a new low-floor center section - these vehicles are not to be confused with other conversions, which were made from 2 Tatra T3 cars each and therefore also have a different door arrangement in the rear section (e.g. B. Plzeň Tatra K3R-NT).
With the development of the K2, a real three-part K3 was also planned. It was never built. It was not until the 1980s that a three-part articulated tram came from the ČKD works. It is the Tatra KT8D5 .
Nevertheless, a three-part articulated wagon was built at ČKD in the 1960s. Namely the ČSD series EMU 89.0 built for the Electric Tatra Railway .

At the beginning of the 70s, a successor to the K2 was considered together with the Tatra KT4 and the Tatra T5A5 8000. There was a drawing and first plans for such a six-axle 2-part articulated train. But like the K3, this project was never realized. The name would be KT6.
