Problems started occurring with Greyhound when the Dial Corporation took over.
Greyhound Buses and Package Express in Canada was a huge success, and ran Greyhound separate from the U.S. Corporation.
The early MC-7 and MC-8 buses had silver caps, which were later painted blue.
The Greyhound Fishbowl buses in California were painted the Pepsi color.
The PD-4107 buses were also painted the Pepsi color.
TMN-O was the name of the Texas, New Mexico, and Oklahoma bus company.
The commuter buses all had Cash Boxes in them.
The Canadian MC-6 buses kept the V12 engine.
Take the Bus and Leaving the Driving to Us became Greyhound's motto.
The MC-7 was the same as an MC-5A, with five feet added to the back end to make them 40’ buses.
See the silver-capped Super-7 Scenicruiser in Thunder Bay, Ontario.
Washington, DC had a Greyhound Airport service bus to shuttle passengers from the airport to the hotels.
