   • 1944 November and December, “"Duplex Roomette" Sleeping Cars”, in Railway Magazine, page 324:

     Although many luxurious single-room sleepers are in service, the demand for sleeping accommodation on long journeys is so great that vehicles less weighty in proportion to their passenger accommodation, and therefore less expensive for the traveller, have become a paramount need, which is largely solved by the roomette car.

   • 1959 November, J. N. Westwood, “The Railways of Canada”, in Trains Illustrated, page 554:

     For most of its journey it is made up to about fourteen cars, of which a large proportion provide the better type of sleeping accommodation (bedrooms, roomettes, etc.).
