Waterloo Central Railway 1978 was built in 1954 by the Canadian Car and Foundry for the Canadian National Railway as coach numbered 5628. It worked on the CNR until 1978 when the newly founded VIA Rail Canada purchased the coach and renumbered it to VIA 5628.
It was used on VIA Rail Canada until 1994 when VIA sold the coach to the British Columbia Railway for use on their Royal Hudson trains. The coach was then renumbered from 5628 to 156280 and was named Sunset Beach, which is the name of a beach along the route of the Royal Hudson.
The coach was used on the Royal Hudson trains until 2003 when CANDO Rail Services purchased the coach for their new Credit Valley Explorer rail tours on the Orangeville Brampton Railway. To commemorate the move, the coach was renumbered to 1978 (The year CANDO Rail Services was founded).
In 2018, the Waterloo Central Railway purchased 1978 from the Credit Valley Explorer. Along with 1978, the WCR purchased coaches 2003 and 6006.
