Metropolitan Railway G Class

The Metropolitan Railway G Class consisted of four 0-6-4T steam locomotives, numbered 94 to 97.^[1] They were built by Yorkshire Engine Company in 1915. The class was unusual by having named engines, and were the last Metropolitan steam locomotives to do so.

Service

The G Class had various roles on the Metropolitan mainline until 1937, when all four were transferred to the London and North Eastern Railway (LNER). The LNER renumbered them as 6154–6157 and reclassified them as M2 Class. Two remained in service until the 1946 renumbering, but all were withdrawn and scrapped from 1943 to 1948^[2]
