Penn Station is New York City's main intercity rail terminal. While the beautiful Grand Central Station serves wealthy Metro-North commuters from Westchester and Connecticut, everyone else (meaning Long Island Rail Road, New Jersey Transit, and Amtrak passengers) is forced to engage with this subterranean shithole, which is hidden underneath Madison Square Garden between 31st and 32nd Streets and 7th and 8th Avenues. The Penn Station stop on the 1/2/3 subway makes it very accessible from Columbia, at least.
History and future of Penn Station
Once, Penn Station was one of the most beautiful shrines to transportation ever built. Then it was torn down in a fit of absence of mind (thanks, Robert Moses), giving birth to an enraged preservation movement. The station remains so hideous that everyone is waiting with baited breath for a replacement, Moynihan Station, to take over most of its functions. The new station will be carved out of the post office across the street from the present station.
