The Park series or Park car is a fleet of lightweight streamlined dome-sleeper-observation cars built by the Budd Company for the Canadian Pacific Railway in 1954. Sixteen of the cars were named for a Canadian national or provincial park, while one was named for a wildlife reserve, and one was named for what was at the time a private park owned by Canadian Pacific subsidiary Dominion Atlantic Railway, but is now one of the National Historic Sites of Canada. Via Rail acquired the fleet from Canadian Pacific in 1978 and the majority of the cars remain in active service.
