TU6SPA (ТУ6СПА) is a Soviet, later Russian diesel locomotive and mobile power station for track gauge.
Diesel locomotive TU6SPA (ТУ6СПА) is a sub-type of the TU8 diesel locomotive equipped with an electric generator used for energy supply to non self-propelled heavy-duty track machines. The TU6SPA was developed in 1987–1993 at the Kambarka Engineering Works to replace the aging locomotive classes TU6SRP (ТУ6СРП). The TU6SPA was designed to be used on any gauge from . The cab is equipped with efficient heat-system, refrigerator, radio-set and air conditioning.[1]
