LSWR Drummond M7 class 0-4-4T No. 479 is depicted here on carriage sidings and ecs duties at Clapham Junction. The shot was probably taken in about 1946 but that's the closest I can get to a date. No. 479 was built in 1911 and served the railways for 50 years with withdrawal coming in 1961 at Eastleigh mpd.
