The shunting locomotive with a hydrogen drive

The shunting locomotive with a hydrogen drive is the result of a modernisation of the SM42. It is the first stage of PESA’s program of implementing hydrogen technologies in rail vehicle drives. The experience gained during the implementation of this project will be the base for the construction of a passenger vehicle with hydrogen drive. Its prototype will be ready in 2025.

SM42-6Dn

The SM42 6Dn locomotive is a 4-axle shunting locomotive with 4x180kW traction motors. Two hydrogen cells /85 kW/ are responsible for generating energy. It is equipped with an autonomous driving system, enabling the driver to control the vehicle by one person while setting up trains, and an obstacle recognition system (anti-collision). SM42-6Dn is distinguished by its new design, with a key change - the location of the driver's cabin in the middle of the vehicle, thanks to which the locomotive has gained a modern look, and the service is more safe and comfortable to work with.
