We were used to seeing Fairburn and Standard 4MT 2-6-4T's on the Brighton main line in south London but a Fowler example was something of a rarity. This is ex-LMSR Fowler 2-6-4T no. 42350 accompanied by an LMSR parcels van on the Up Slow line between Wandsworth Common and Clapham Junction stations. Although not dated no. 42350 was allocated to Willesden mpd from 9/59 until 5/63 and so this shot was taken between those dates.
