when did the last steam train run on the london underground
Metropolitan Railway steam locomotives In 1933 the Metropolitan Railway was absorbed into the newly created London Passenger Transport Board and on 1 November 1937 the later G, H and K Class steam locomotives were transferred to the London and North Eastern Railway (LNER) who took over all freight workings and became responsible for hauling passenger trains with steam locomotives north of Rickmansworth. From the early 1940s these were replaced by ex Great Central Railway locomotives, now classified LNER Class A5. These were replaced by LNER L1s after 1948 and ten years later in 1958 when the joint line was transferred to British Railway's London Midland Region former LMS locomotives replaced the L1s.[20] Steam working ended on passenger trains after the introduction of the A Stock in 1961.[21]
