The first prototypes appeared at the Bryansk factory in 1960, with several pilot batches of locomotives built before full production began in 1967.

Exported to Poland and Cuba, the Polish units can be seen on the standard and broad-gauge rail lines in the country.

The work involved upgrading the underframe of the unit and installing new components, including a 900 kW C32 Caterpillar diesel engine, EMIT main and auxiliary generators, a new Airpol SK30 compressor, and a remote fuel metering system.

The unit also had new control circuit wires and power cables and video surveillance cameras installed.

Cab upgrades include a new control panel, a new chair, HVAC system, and ultraviolet lamp for disinfection of frequently touched surfaces.
