The Tatra T5B6 was an experimental tramcar built in 1976 by ČKD Tatra.

History

Having enjoyed widespread success throughout the Soviet Union with its earlier products, Tatra were keen to develop a new, modernised generation of tramcars for its clients. After initial runs on test-track at the Tatra factory, two prototypes were delivered to Most for evaluation, where they spent a year. The transport authorities in Most were however unwilling to pay a higher price for the T5B6 than they would otherwise have paid for the T3SU and no more orders were placed. The original prototype is still in Most, however it does not see active service and is kept only as an historic vehicle.
