GWR Railcar nos 5 -16.
In 1933, the Great Western Railway introduced the first of what was to become a very successful series of railcars, which survived in regular use into the 1960s.
The original design featured streamlined bodywork, which was very much the fashion at the time. The rounded lines of the first examples built led to their nickname: "flying banana".

Sideplates were removed to make maintenance easier.
