It’ll be at least 4 years before Santiago Calatrava’s scaled-back, over-budget World Trade Center PATH station is completed (though as our upcoming feature on Lower Manhattan showcases, everything’s been a long time coming, but it seems to have finally arrived). Still, from the start of the interminable process, we’ve had some of the flashiest renderings around to tuck us in at night. Now comes an illustrated video courtesy the Journal‘s Metropolis blog that gives us our clearest view yet of just what’s planned, as well as what Calatrava meant when he told the New Yorker a while back that he was striving for something akin to Grand Central—a truly great room where the interiors, not the exteriors, would be what truly matters. If this video is any indication, despite all the cutbacks, he’s succeeded grandly.
