Isn't it right across the street from the current station?
One long block away.
And in the wrong direction.
The current Penn station is in an out of the way place to begin with.
Not midtown and not downtown.
Unlike Grand Central Terminal, Most Penn Station commuters who work in midtown have to hop one or more buses and subways to get to their offices or walk a half mile or more.
Moving the station more to the west is moving it even further away from where people are going--and one l-o-n-g block further away from everything if you like to walk.
Hey, I like architecture--and the Farley post office is a nice building for something so grotesquely huge.
But I'd rather see them move Penn station to midtown or downtown, even if they have to put it in an old warehouse to do it.
P.S. While I bemoan the demolition of so many of Manhattan's beautiful old buildings--I cannot understand why so many people morn the demolition of the old Penn station--which with its ungainly looking skylight always seemed a white elephant to me.
Although what they built in its place is even uglier.
