The earliest railway carriages all had compartments. Open plan carriages were introduced in 1874, in Pullman cars, although many passengers preferred the privacy of a carriage. By the 1930s the railway companies were starting to adopt open plan carriages, although the Great Western railway preferred to keep its compartments.
