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.{{Cite book |last=Bruce |first=J Graeme |title=Steam to Silver |publisher=Capital Transport |year=1983 |isbn=0-904711-45-5 |edition=Fully revised |location=Harrow Weald, Middlesex |pages=88 |language=en}} 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 (even numbers only), were initially owned by the London Midland and Scottish Railway.{{Cite book |last=Bruce |first=J Graeme |title=Steam to Silver |publisher=Capital Transport |year=1983 |isbn=0-904711-45-5 |edition=Fully revised |location=Harrow Weald, Middlesex |pages=89 |language=en}}

The L Stock was based on the 1927 K Stock.

Fate

The conversion from L Stock to Q31 Stock took place in the late 1930s, with the major modifications being the conversion of the hand-operated sliding doors to air operation and the provision of electro-pneumatic brakes.{{Cite book |last=Bruce |first=J Graeme |title=Steam to Silver |publisher=Capital Transport |year=1983 |isbn=0-904711-45-5 |edition=Fully revised |location=Harrow Weald, Middlesex |pages=96 |language=en}} The last Q Stock trains were withdrawn in 1971.
