West Side Yard is a 26-acre train depot in Manhattan. You know how important trains are to New York City, but you might also have some idea of how valuable land in Manhattan is. The train yard must stay, but that acreage will be developed into skyscrapers, business, and housing anyway. Hudson Yards, a private development leasing space from the city, will be built on a platform above the train yard. There will be four skyscrapers on the corners. How they’re going to do it is explained at Gizmodo. Just think: in another hundred years, people will consider the train yard as being underground, and assume that it was originally planned that way. -via Digg
