The Château series is a fleet of 29 lightweight streamlined sleeping cars built by the Budd Company for the Canadian Pacific Railway in 1954.

Via Rail acquired the fleet from the Canadian Pacific in 1978 and the cars remain in active service.

The cars were constructed of stainless steel; save for a Tuscan red letterboard bearing the name "Canadian Pacific" they were unpainted.

As built each contained eight duplex roomettes, four sections, three bedrooms, and one drawing room for a maximum capacity of 25 passengers.

The four open sections were located at the front of the car, followed by the three bedrooms and one drawing room, and then the eight duplex roomettes.
