London Underground Q38 Stock

In the 1930s the London Underground's District Line converted older G Stock to have air operated doors, these were re-designated Q Stock. New motor cars and trailers were also built to operate with the older stock as the Q38. Twenty five Driving Motors and 183 trailers were built, these were similar to the previously built O and P Stocks with a flared skirt on the sides. The trailers has driver cab doors at one end for possible future conversion to DM in future. In service these operated with older Q Stock which didn't have these flares and had clerestory roofs which gave the trains a strange appearance.
