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, when they were replaced with the new British RailFirst Generation type Diesel multiple units.

Preservation
Three of the GWR Railcars have survived into preservation, as follows:
Railcar 4 is now preserved at the Steam museum in Swindon.
GRCW bodied railcars 13 and 14 were later converted to parcels use as well.
The pioneering railcar was also, according to this book, withdrawn from Reading by British Railways in May 1957, its last GWR shed being Llantrisant in 1947.
The name of the photographer of the rather grainy fl and white photograph below is not known nor is there any information to indicate the date when the photograph was taken.
What is clear is that the railcar is in Worcester Shrub Hill's station up platform presumably having arrived from either the Malvern or Kidderminster directions.
Railcar W23W was built in 1940 and was one of the last to withdrawn from service at the end of the Summer 1962 timetable.
