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".
Gloucester RCW built 3 new railcars to a slightly improved design with sliding doors. These few followed up with 9 more. Toilets were added to some and other small changes were also introduced.
Sideplates were removed to make maintenance easier.
Original with side plates
Requires chasssis, bogies, interior and finishing.
