Loading-transport railmotor car МПТ-4

The railmotor car is a self-propelled two-axle vehicle. Power plant (diesel ЯМЗ-238 Б-14) is on the rear stand under a cowl, it transmits power through a wedge-belt transmission to a three-phase generator and through a hydro-transmission and a cardan drive - to the axle reducers of the wheel pairs and a compressor.
