During the declining years of the branch line through the 1950s and into
the 1960s many branch trains required just one coach, making this
single brake composite ideal for replicating many ex-GWR branch lines in
their final years and makes for a great saving in train length!
accommodation for first and third class passengers plus the essential
guards' van and handbrake these coaches were used for single coach
trains and as 'strengthening' coaches to add capacity to the most
popular suburban services, maintaining an appropriate proportion of
first class compartments within the train.
