Manufacturer description
The Turbomotive was an experimental steam locomotive built in 1935 by the London, Midland, and Scottish Railway (LMS) under the direction of Chief Mechanical Engineer William Stanier. Based on the successful Princess Royal Class design, the Turbomotive stood out for its use of a steam turbine instead of traditional reciprocating pistons.
This turbine arrangement allowed for smoother, quieter running, and fewer mechanical parts, which theoretically meant reduced maintenance and greater reliability at sustained high speeds. It was especially efficient on long-distance, high-speed runs where constant power was required.
However, the lack of a reliable reverse gear and reduced flexibility at lower speeds or for shunting limited its practical application. Despite promising performance, the complexities of turbine technology in rail use led to the project being discontinued. After World War II, in 1949, the Turbomotive was rebuilt as a conventional piston-driven locomotive, marking the end of Britain’s brief experiment with steam turbine propulsion in railways.
