On 12th June 1961, a strange space age looking train pulled into Watford for the first time. Today, 50 years later, the units are still rolling into Watford as well as Amersham, Chesham, Aldgate & Baker Street. Built by Cravens of Sheffield, the A Stock is currently the oldest type of train in passenger service on London Underground, and the last rolling stock to have independent motoring and braking controls.
The trains were designated as the A Stock to mark the electrification of the Metropolitan Line to Amersham. However the A Stock was also used on the former East London Line until the line’s closure for conversion to the London Overground network on 22 December 2007.
The A stock design was a compromise between the needs of longer distance “outer suburban” passengers on the outer reaches of the line and short distance “urban” passengers over part of the heavily used Circle and Hammersmith & City lines.
When built they had a top speed of 70 mph (110 km/h) (The World’s Fastest Fourth Rail Electrified Train), and operated at this speed until the late 1990s/early 2000s. They are now permitted to travel at no more than 50 mph (80 km/h) to improve reliability. Despite this, these trains are still the fastest on the London Underground network.
Recently, the ‘A’ Stock units have started to be replaced by brand new ‘S’ Stock trains which are beginning to enter service as far as Baker Street. ‘A’ Stock units are being withdrawn to Neasden Depot, stripped of useful components and removed by road from Northwood to be scrapped.
