Metropolitan Railway Bo-Bo No.12 Sarah Siddons passes through Wraysbury station whilst working the 12:13 Staines to Windsor & Eton Riverside special during the Network SouthEast Windsor & Eton Gala Day on 10 December 1989. Built by Metropolitan Vickers at Barrow-in-Furness in 1922, Sarah Siddons survived in London Transport departmental use and outlived the other members of the twenty strong class. Part of the rebuilding work carried out on the locomotive in 1982 allowed it to work on the Southern Region's 750V DC third rail system in addition to the London Transport lines. The Windsor & Eton Gala was an ideal opportunity to photograph this fascinating loco on the main line, but unfortunately as can be seen here the weather was abysmal!
