The G Stock were 50 electric multiple unit train carriages built for the District Railway in 1923 by Gloucester RC&W.[1] They operated on the District line of the London Underground until 1971 (with most cars being withdrawn in the early 1960s).

## Construction

[edit]

The G Stock was built to allow the scrapping of some of wooden-built 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

[edit]

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.[2] A major part of the 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.[3]

## South Acton shuttle

[edit]

The two remaining cars were rebuilt into single cars for use on the South Acton shuttle, replacing a B Stock car. These two cars, numbered 4167 and 4176, were not rebuilt into Q Stock and were classified G23 Stock.[2]

In 1965, several cars were renumbered by adding 100 to the number to avoid conflicting numbers with the 1967 Stock being built for the Victoria line.

## Withdrawal

[edit]

The majority of the cars were withdrawn in the early 1960s as CO/CP Stock trains transferred from the Metropolitan line started to become available. The last of the Q Stock was withdrawn in 1971.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