> Let people wait on the platform as the train arrives. This is something that basically every train operator but Amtrak does. I haven't been to penn station in a while but I know the LIRR track numbers aren't available until the train arrives or right before. This dictates which platform to stand on. Basically you end up standing in a huge open lobby and eventually a big display says to goto track 21, then there's a mad rush of people making their way to track 21 which involves leaving the lobby, going down stairs, and making your way to the track to board the train.
