11), twin motor NB: Production of the last-mentioned class continued after Nationalisation, with the following two locomotives emerging as M7130 and M7131 (later 12043/12044) and the remainder carrying BR numbers 12045–12138 from new. Although allocated TOPS Class 11, none of these locomotives were renumbered. When 12082 was re-registered for use on the mainline, it was allocated TOPS number 01553 in the ex-industrial registered shunters list. Departmental 2 later renumbered ED1 This locomotive was very similar to the Great Western Railway's diesel locomotive number 1. Trial locomotives The LMS used a number of locomotives on loan from their manufacturers for trials. These locomotives were not allocated LMS numbers, and details of their use and disposal are sketchy. Such locomotives included: Vulcan – a diesel-mechanical 0-6-0 shunter built at the Vulcan Foundry, Newton-le-Willows, in 1936. It had a Vulcan-Frichs 6-cylinder diesel engine. After loan to the LMS, it was used by the War Department, which numbered it 75 (later 70075). Following the end of World War II, it found industrial use in Yugoslavia. (Unnumbered) – an Armstrong-Whitworth/Sulzer shunter built in 1932, which was an earlier version of the LMS's own 7408/7058. This locomotive was also loaned to the London and North Eastern Railway for trials.
