London Underground K Stock
Encyclopedia
London Underground K Stock is a clerestory
-roofed rail stock built for the District line
in 1927. It was subsequently absorbed into the London Underground Q Stock
.
A complete review of District line rolling stock was carried out in 1926, leading to the withdrawal of further B Stock cars and their replacement, plus additional rolling stock to increase frequencies. This led to the construction of the K Stock, some of which was owned by the London, Midland and Scottish Railway
(LMS).
As built, the cars had hand-operated sliding doors. The doors were converted to air operation in 1938 as part of the Q Stock project. The modified cars were reclassified as Q27 stock. The last of the Q Stock was withdrawn in 1971.
