). The rebuild therefore inherited the same number (1831), although little of the steam locomotive was actually re-used. 1831 was not successful, but it did provide useful data for the further development of the diesel shunter design. It was withdrawn from service in September 1939 and converted to a mobile power unit, emerging in its new guise as MPU3 in November 1940. It was scrapped in the 1950s (sources vary as to exactly when).

7400–7408 later renumbered 7050–7058

A further nine prototype locomotives were built 1932-1935 by a variety of manufacturers. These were built allocated the number series 7400–7408. These were allocated the number series 7400–7408, but the LMSR soon realised that this number range was too limited for the number of production diesel shunters that were anticipated, and a new number series commencing with number 7050 was used. Only 7050–7053/7058 carried their original numbers (7400–7403/7408), and they were all renumbered in November/December 1934, some before they had actually entered service.
