LMS 1831

In 1931 the LMS, at it's Derby Works, rebuilt a steam locomotive as a diesel shunter, the first of a number of experimental diesel shunters built by the "Big 4" railway companies in the 1930s. The original steam locomotive was a Midland Railway 1377 class steam locomotive. The locomotive was rebuilt and fitted with a Paxman diesel engine and Haslam & Newton hydraulic transmission [1].

1831 after construction [3]

The locomotive had a very box-like body with small cab windows. The locomotive was not a great success. It was withdrawn from service in 1939 after a number of years in storage. It was converted into a mobile power unit [2] and survived in this guise until 1951.
