 shunters produced by the LMS is summarised below. In each heading, the first number(s) carried are shown first, with subsequent renumbering(s) following the "/".

Note on numbering

The initial experimental diesel shunter retained the number of the steam locomotive that it was nominally rebuilt from. However, when the LMS decided to procure a further nine prototype locomotives from a variety of manufacturers, it allocated the number series 7400-7408 to them. It was soon realised that this number range was too limited for the number of production diesel shunters that were anticipated, and a new series commencing at 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.

, whose number it inherited (1831), though very little of the steam locomotive was actually re-used. Of itself, it was not very 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 It was withdrawn from service in September 1939 and converted to a mobile power unit, emerging in its new guise as MPU3 in November 1940.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 disagree exactly when).
