Sleepers include a bed and usually a private washbasin, towels and bed linen and can accommodate up to four passengers in single, double, or 3-person compartments. Couchettes offer simple overnight accommodation that sleeps up to six people on bunks, with a pillow and blanket provided.
Bedrooms have a toilet in an enclosed compartment which is also a shower. There is also a sink in the room itself. Roomettes have no sink or toilet facilities except on some cars on single level trains. Accessible rooms on single level sleeping cars have the same facilities as bedrooms, above.
To put things simply, a sleeper is essentially a car that other drivers might not expect to perform in a certain way. You could even say other drivers might underestimate these vehicles. A sleeper vehicle is fast, powerful, and efficient, but not always flashy.
