This film introduces the innovative Fell Locomotive, a diesel-powered train with a unique transmission design. In 1951, this locomotive, named after its designer Colonel Fell, emerged as a new approach to main-line traction.
The Fell Locomotive, on the other hand, employs a direct diesel engine with a novel transmission system inspired by a car's differential. It uses three differentials connected to four engines. Initially, only one engine is engaged, with a 4:1 gear ratio for smooth starting. As speed increases, additional engines are activated, resulting in a seamless transition through all speeds, achieving a final ratio of 1:1 with all four engines running.
