Roomette

1945 ad by the Budd Company for its "Budgette" cars.

A roomette is a type of sleeping car compartment in a railroad passenger train. The term was first used in North America, and was later carried over into Australia and New Zealand. Roomette rooms are relatively small, and were originally generally intended for use by a single person; contemporary roomettes on Amtrak, however, include two sleeping berths.
