HISTORY. Recently restored to traffic Metropolitan Vickers built loco 'Sarah Siddons' dating from 1921 is seen alongside the A60
stock which finally ended these loco's passenger workings  on London Undeground's Metropolitan line in 1961. No 12 however was
to continue in service for many years to come in an engineering capacity and later actually made it onto the Southern Region on a charter! The
date of this picture was the 5th June 2007 at Rickmansworth when 'Sarah' was doing some proving runs prior to a forthcoming special.
