Greyhound scenic cruiser in the day. Trailways also ran a couple of these older models when I was there. They were known as 'freighters' because of their cavernous cargo holds.
I always felt we had a pretty congenial relationship with Greyhound, but as far as routes & territory, it was a different story. This was worked out between managements and in the courts. I saw the same issues with TWA and UAL and think it is just part of the business of transportation.
