The G Stock was built for the Metropolitan District Railway in 1923 by Gloucester RC&W.

In 1938, forty-eight of these units were rebuilt when the District Line was standardising its post-1923 stock and were reclassified as Q23 Stock. 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.

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.

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.

Two driving motors have been preserved.
