The '''G Stock''' were 50 [[electric multiple unit]] [[train]] carriages built for the [[Metropolitan District Railway]] in 1923 by [[Gloucester Railway Carriage & Wagon Company|Gloucester RC&W]]. They operated on the [[District line]] of the [[London Underground]] until 1971 (with most cars being withdrawn in the early 1960s).

==Construction==
The G Stock was built to allow the scrapping of some of wooden-built [[London Underground B Stock|B Stock]] trailer cars which were in poor condition. Some steel-framed B Stock motor cars were converted to trailers, themselves being replaced by new G Stock motorcars. The G Stock consisted entirely of motor cars, all built with a [[clerestory]] roof similar in style to the B Stock with which they would work.

==Q Stock==
In 1938, forty-eight of these cars were rebuilt when the [[District Line]] was standardising its post-1923 stock and were reclassified as '''Q23 Stock'''. A major part of the [[London Underground Q Stock|Q Stock]] project was the replacement of the potentially dangerous manually operated sliding doors (which could be opened by passengers between stations) with air operated doors controlled by the guard.

==South Acton shuttle==
The two remaining cars were rebuilt into single cars for use on the [[South Acton]] shuttle, replacing a [[London Underground B Stock|B Stock]] car. These two cars, numbered 4167 and 4176, were not rebuilt into Q Stock and were classified '''G23 Stock'''.

In 1965, several cars were renumbered by adding 100 to the number to avoid conflicting numbers with the [[London Underground 1967 Stock|1967 Stock]] being built for the [[Victoria Line]].

==Withdrawal==
The majority of the cars were withdrawn in the early 1960s as CO/CP Stock trains transferred from the Metropolitan line started to become available. The last of the Q Stock was withdrawn in 1971.

Two driving motors have been preserved.
