Montgomery Double & Medium-File Escalators - Marriott Downtown - Philadelphia, PA

This is a pretty neat hotel that is full of Montgomery! These are the escalators that go from the lobby up to the meeting rooms. They're Montgomery double-file escalators. When I got to the top, I saw that there was another sets that went up one more floor, and those were medium-file escalators. There was even a third set that went up even more, but I was short on time and I didn't like the configuration. They're pretty much a same though
