Background
The GX-2 was a prototype bus built for Greyhound that was eventually developed into the Scenicruiser. It began in mid-1948 as a 35-foot design, but, in part to accommodate more passengers, Greyhound President Orville Caesar directed his engineering department to add five feet in length to the upper deck of a PD-3751 obtained from GM. After Greyhound's initial experiences with GX-1, a 50-seat double-decked bus, Caesar decided that the next prototype would be a deck-and-a-half style, which led to the silhouette of the Scenicruiser.
