The LMS Turbomotive was a modified LMS Princess Royal Class steam turbine locomotive designed by William Stanier and built by the London, Midland and Scottish Railway in 1935. It was inspired by the Swedish Ljungström locomotives first introduced in 1922. It used turbines instead of cylinders. It was later rebuilt as a conventional locomotive No. 46202 Princess Anne.
