LMS diesel shunter 7051 was built by the Hunslet Engine Company to demonstrate its wares.

History

After public exhibition in February 1932 it was trialled at a colliery before being tested by the LMS, and after further exhibition in February 1933, it was purchased by them in May of that year.

It was loaned to the War Department from August 1940, which numbered it 27. From 1941 to 1944 it was returned to the LMS but sent back again in August 1944, now numbered 70027.

The LMS took it back once more after the war, but was withdrawn in December 1945 and resold back to Hunslet. Hunslet used the locomotive as a works shunter, but it was also available for hire and occasionally loaned to oil refineries in Essex and British Railways.

In September 1960, the locomotive was preserved by the Middleton Railway ^[1] in Leeds and named John Alcock, named after the then current Managing Director of Hunslet Railway Company. It remains at the Middleton Railway, but has spent time on loan to other locations, including the National Railway Museum in York.
