There is a lounge with seating, you just need a ticket

Its been a few years since I've had to go through Penn Station directly other than for LIRR. As I recall from my NE Corridor commuting days the lounge requires an Amtrak ticket. The NJ Transit waiting area had no lounge and no seats meaning people would begin to bunch up on the stairs. Admittedly, it might have changed in the intervening years.

Theoretically, it's Acela only I believe but in my experience no one cares.
