Snowdon Mountain Railway invests in future with new hybrid diesel locomotives

Snowdon Mountain Railway has begun a programme of replacement for its existing diesel locomotives which began service in 1985.

The 123 year old railway began looking into replacement locomotives five years ago, after extensive market research and specification development.

The new 800mm gauge hybrid locomotives will be driven by High Torque, maintenance free electric motors, and powered by traction battery and diesel generator. As Snowdon Mountain Railway is an Abt Rack and Pinion Railway, the traction and braking is all taken through the pinions. On descent from the summit the diesel generator will be switched off whilst service braking recharges the battery ready for the locomotives next accent.
