The British Rail Class 11 was applied to a batch of diesel shunting locomotives built from April 1945 to December 1952, based on a similar earlier batch built by the London, Midland and Scottish Railway (LMS) between 1934 and 1936.

Overview
Numbering
An initial batch of twenty locomotives was built during World War II, fourteen of which were built for the War Department, with the first ten of these (70260-70269) subsequently going to the Nederlandse Spoorwegen post-war as NS 501–510. LMS numbers 7120–7126 went straight into LMS stock, and a follow-up batch was built, 7129 being the last diesel shunter to be built for the LMS. British Railways continued to build the class from 1948 to 1952, using numbers M7130–M7131 and 12045–12138. 7120–7129 and M7130–M7131 became BR numbers 12033–12044. The whole class of 12033–12138 became Class 11. Locomotives up to 12102 were built at LMS/BR Derby and 12103–12138 at BR Darlington.
Export locomotives
Close to 100 almost identical machines were built by English Electric and supplied to Nederlandse Spoorwegen (NS) as their 500 Class & 600 Class diesel locomotives. In addition to the exported 501-510 mentioned above, 500 Class also included 511-545. Sixty-five of the 600 Class locomotives were built by English Electric between 1950 and 1957, numbered 601–665, at either Dick, Kerr & Co. Works (601–610) in Preston or Vulcan Foundry Works (remainder) in Newton-le-Willows. A further batch of 15 locomotives were exported without engines so that they could be fitted as such in the Netherlands. These were numbered 701-715.
Another export order was to Australia, with 16 locomotives built in 1951 but with the design modified for use on 5 ft 3 in gauge railways. The Victorian Railways bought ten, which were designated as F class, and six were bought by the State Electricity Commission of Victoria for shunting on sidings connected to Victorian Railways tracks.[1]
One of the Class 11, was built to be transporting British soldiers in the Nazi captured countries. It has throughout the liberations, travelled through France, Belgium, Netherlands to finally reaching Nazi Germany. It was then used to transport British troopers and shunting, few times used on few branch lines until 1957. The reason was that after the war, the new founded Deutsche Bundesbahn, was slowly building up their locomotive fleet again. As the more powerful German engines began to roll out, the Class 11 was lesser used and in 1953 it was withdrawn and stood in Hamm Engine shed, in West Germany until it was bought by the Danish State Railways in 1957. It was then renumbered to DSB ML 6 and was repainted in the dark green that the Danish diesel shunters was painted in , and served with shunting in Copenhagen shunting yards until 1973, where it was finally withdrawn for good. Later scrapped in 1974 in Hedehusene in Denmark. [2]
Technical details
The diesel engine is an English Electric 6-cylinder, 10-inch bore by 12-inch stroke (254 mm by 305 mm); 4-stroke, 6KT and the traction motors are two: EE506 axle-hung, nose-suspended, force-ventilated traction motors with 21.7:1 double reduction gear drive. The main generator is an English Electric EE801, 441 A at 430 V.
Withdrawal
The 106 locomotives of British Railways were withdrawn between May 1967 and November 1972

Post-BR use
Sixteen locomotives were sold to the National Coal Board, and were used in the North East, South Wales and the Kent Coalfield.[4]
The following locomotives were at Harry Needle Railroad Company (HNRC):[when?]
- 12074 Scrapped
- 12088 sold to the Aln Valley Railway.
- 12098 Scrapped
Preservation
The following Class 11 diesel shunters are preserved:
- 12052 at Caledonian Railway
- 12077 at Midland Railway - Butterley
- 12083 at Battlefield Line Railway
- 12088 at Aln Valley Railway
- 12093 at Caledonian Railway
- 12099 at Severn Valley Railway
- 12131 at North Norfolk Railway
- A ninth example 12049 (renumbered from 12082) is preserved at the Watercress Line in Hampshire. At one time it was re-registered as 01553, in TOPS Class 01/5, carried both numbers and was owned by the Harry Needle Railroad Company. 12082 was renumbered to 12049 in October 2010 and painted in BR green with a late crest but without the yellow/black ends. This was as a replacement for the original Mid Hants locomotive 12049 that was scrapped after suffering catastrophic damage during an engine shed fire on 26 July 2010.[5]
