This locomotive is a Ruston Hornsby built in 1958 to work on the Alderney breakwater. Due to limited craneage facilities Molly was sent over in kit form and has large slab weights attached to her sides to improve her rail adhesion. Molly has an 88 BHP four cylinder Ruston diesel engine. She is unable to haul the tube cars as she features US style couplings and she has a restricted compressed air charging system. Molly came into the ownership of the Alderney Railway a few years ago having been previously owned by the States of Guernsey. A complete refurbishment (mechanicals and body work) is being undertaken.
