Guys. I am pretty sure that is Moynihan train station next to Penn Station. People sitting on the floor are literally leaning against the stairs down to the track. Thats is where people lineup to go on the train when it arrives at the station. Of course you don’t put benches there. In this station there is a seating area where all you need to do is show your train ticket. On the other side there’s a food hall with lots of public seating. There just isn’t seating directly where all the foot traffic is. I take trains in the North East corridor on Amtrak somewhat often. There’s seats there. Just not where seating would obstruct movement on and off the train platforms.
