In Greyhound schedule 742, there are buses by GLI, ADT, and NYP. GLI is Greyhound LInes, ADT is Adirondack Trailways, but what does NYP stand for? It's the code for the Amtrak New York Penn station but that doesn't seem related. Is it New York Trailways? But then what's the P for?
Actually NYP = Pine Hill Trailways. Pine Hill along with Adirondack and New York Trailways operate under the same umbrella of New York Trailways, hence NYP(New York Pine Hill).
