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