5″ LMS 1831

Here we have a nice little engine and again something a bit unusual.  This is a 5″ gauge representation of the LMS prototype diesel shunter No. 1831.

No. 1831 was the first experimental diesel hydraulic shunter in the UK. It was introduced in 1932, built at Midland Railway’s Derby works. It was nominally a rebuild of a Midland Railway 1377 Class 0-6-0T steam locomotive of the same number. 

The experiment was not a success and the locomotive was put into storage in 1936. 1831 was withdrawn from service in September 1939 and converted to a mobile power unit, emerging in its new guise as MPU3 in November 1940. It was scrapped in August 1951.

The model is very heavy and powered by a neatly packed in 36cc BSA petrol engine driving through a centrifugal clutch.
