LMS diesel shunter 7050 is an experimental 0-4-0 diesel-mechanical shunting locomotive, introduced by the London Midland and Scottish Railway (LMS) in 1934 and which remained in service with that railway for six years.

7050 was an experimental locomotive built by the Drewry Car Co. at the English Electric Preston works in 1934.

For six years it was used for dock shunting at Salford before being loaned to the Air Ministry in 1940.

[1] It was withdrawn from LMS stock in March 1943 and sold to the War Department (WD) which numbered it 224.

At some point it was rebuilt with a Gardner engine and was used at the Royal Navy base at Botley, Hampshire.
