The British Rail Class 11 was applied to a batch of locomotives built from April 1945 to December 1952, based on a similar earlier batch.
LMS numbers 7120-7125 went to the War Department and then into LMS stock. LMS numbers 7126-7129 went straight into LMS stock, with 7129 being the last diesel shunter to be built for the LMS. British Railways continued to build the class from 1948-1952, being numbered M7130/1 and 12045-12138. 7020-7129, M7130 & M7131 became BR numbers 12033-12042. 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.
The engine is an English Electric 6-cyl, 10? bore by 12? stroke; 4-stroke, 6KT and the traction motors are 2 x 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.
