That's quite a creation, Lee. It would be great to have a Greyhound Scenicruiser running around on a layout.
I too, rode these things when I was a teen back in the sixties, from San Francisco to Los Angeles and from Los Angeles to Salt Lake City. My last ride on one was from Travis AFB to the San Francisco airport back in Navy days, 1974.
Here's one I have, but it has to be hauled around by a UP freight train.
Great job.
