Greyhound operated through interline trips all over North America with a multitude of carriers’s. In most, but not all cases, the pool carrier equipment had to be up to Greyhound standards, and be in a similar blue, white, and silver color scheme, even if the “regular” scheme differed.
SMT (Eastern Limited) buses did indeed come into The Port. IIRC, at one time there was even a summertime thru trip all the way to Halifax, involving Acadian Lines.
Another “exotic” pool was a New York to Quebec City via Newport, Vermont with Quebec Central Transportation Company.

……It was just “Maritimes”…and I seem to recall seeing this on Greyhounds heading up I-95.
(And that roll-sign in the link above….almost as fun as watching the old Solari Board at Grand Central flip through all those long gone named trains and destinations !!)
