Greyhound Scenicruiser

A 1955 GM PD-4501 Scenicruiser in Greyhound colors at the Pacific Bus Museum, California, in 2018. General Motors built about a thousand for Greyhound between 1954 and 1956, and the split-level layout put most passengers on a raised rear deck with a wraparound view of the highway. It was air-conditioned and had a restroom on board, and for a generation of Americans it was what a long-distance bus trip looked like.
