The rare sight of a 47XX 2-8-0 on passenger work, at Mitre Bridge in 1957. Only on Summer Saturdays were these 'Night Owl' 47XX class 2-8-0s employed on express work, usually as here on the 12.5pm Paddington - Plymouth, Saturday 31/8/57: no. 4700 (built 5/19, withdrawn 10/62) is approaching Old Oak Common East. [Apologies for the poor quality, but perhaps justified by rarity].
