Edgware Station Northern Line. Built during the extension of the London underground system during the 1930s the line was originally intended to continue north to Bushey. In anticipation of this a depot was built at Aldenham. Unfortunately World War 2 disrupted these plans and construction was suspended whilst the depot became an aircraft factory. After the cessation of hostilities the extension was abandoned and Aldenham became a bus overhaul works. It featured in the film "Summer Holiday".
