The so-called LMS Twins, a pair of 1,600hp diesel electric locomotives that had been designed and built at the British Railways Locomotive Works at Derby in 1947–48, were proper prototypes. They were both right at the leading edge of railway design of the time, and needed to be thoroughly tested. By 1953, both locos had been updated and modified, and were moved to the Southern Region for more testing. They were joined by their larger cousins, 10201, 10202 and 10203, designed by the former CME of the Southern Railway, OVS Bulleid.
By the end of the 1950s, diesel traction was entering the BR fleet in numbers, and the prototype diesels were moved back to Derby make it easier for maintenance. Relegated to secondary duties, and painted in less flamboyant liveries, all five prototypes were eventually withdrawn and scrapped. 10001 lingered at Derby until 1966. Sadly, none of these locos were considered worthy of adding the national collection. There is an organisation trying to build a recreation 10000, the pioneer loco from 1947.
This commission build was to make a representation of 10001 as it appeared in 1953. Various updates and modifications were made to the Just Like The Real Thing kit, such as revised roof grilles and the air horn brackets this loco featured until 1954. The client requested a light weathering, so I’ve aimed for grubby but cared for. The bogies showed the grime a lot, being finished in an aluminium silver paint, so I’ve concentrated dirt round there.
This is my second 10001 build. The previous one represented the loco in its as-built 1948 condition.
