London Underground L Stock
London Underground L Stock was a clerestory-roofed rail stock built for the District line in 1932 and subsequently absorbed into the London [Underground Q Stock], being redesignated Q31 Stock.
History
The L Stock trains were built to provide additional rolling stock for the eastward extension of the District Line from Barking to Upminster. Two new electrified tracks were added parallel to the existing steam-operated LMS lines, including several new stations such as Upminster Bridge.Forty-five cars were built by the Union Construction Company, eight were driving motor cars and the rest were trailers. An innovation for surface stock was the provision of a sliding door at the guard's position. The eight motor cars, numbered 700-714, were initially owned by the London Midland and Scottish Railway.
The L Stock was based on the 1927 K Stock.
