The stock was built in two batches (A60 and A62) by Cravens of Sheffield in the early 1960s and replaced all other trains on the line. At the time of its withdrawal in September 2012, the stock was the oldest on the Underground, and on any Subway system in Europe. It was the only stock to have luggage racks, umbrella hooks and separate motoring and braking controls, and the last to have no automated announcements. ==Development and introduction== The design was formulated by W S Graff-Baker of the London Passenger Transport Board as part of the electrification of the Metropolitan line from to and under the 1935–1940 New Works Programme, and owes much to the smaller 1938 Stock. The project was delayed by World War II and lack of funds during the austerity period after the war. In 1946 two experimental trailers similar in exterior appearance to the production trains were built using underframes from T Stock, but they were scrapped when the trials concluded. Graff-Baker died in 1952, before the trains were finally built. When electrification commenced in 1959, London Transport placed an order for 31 trains ''A60 Stock'' trains to replace T Stock on services to Watford and Rickmansworth and locomotive-hauled services to destinations north of Rickmansworth. The first units, 5004 and 5008, entered service to Watford in June 1961.〔〔〔 The Amersham/Chesham services began later that year. London Transport later ordered 27 trains ''A62 Stock'' trains, introduced in 1961–63 to replace F and P Stocks on the Uxbridge service. By December 1963, the roll-out was complete.〔 The trains were A Stock to mark the electrification of the Metropolitan line to ''A''mersham. Four-car units were used on the East London Line (then a branch of the Metropolitan line) June 1977-April 1985, May 1987-24 March 1995 and 25 March 1998 – 27 December 2007, when the line closed to become part of the London Overground network.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「London Underground A60 and A62 Stock」の詳細全文を読む スポンサード リンク
