TheLSWR M7 classis a class of0-4-4passengertank locomotivebuilt between 1897 and 1911. Drummonddesigned the class for use on the intensiveLondonnetwork of theLondon and South Western Railway(LSWR), the locomotive proved to be well suited to such tasks. Because of their utility, 105 were built, 95 being built at Nine Elms Works with the remaining ten being built at Eastleigh Works. The class went through several modifications over five production batches. For this reason, there were detail variations such as frame length. Many of the class were fitted for push-pull operations, that enabled efficient use on branch line duties.

Under LSWR andSouthern Railwayownership they had been successful suburban passenger engines, although with the increased availability of newer, standard designs, many of the class were diagrammed to take on a new role as reliable branch line engines, especially inSouthern England.

Many of the class also entered service with British railways. With members of the class lasting in service until 1964 Two examples have survived into preservation: number 245 in theNational Railway Museum, and 53 (as BR 30053) on theSwanage Railway. The rest of the class were scrapped. One locomotive was withdrawn in 1937, one in 1938 and the remainder being withdrawn between 1957 and 1965.
