The High Line park comes to an abrupt end on the west side of Manhattan, as a chain link fence keeps anyone from stumbling into a massive train yard that handles much of the island’s commuter rail traffic.
Within a few years, that fence be will gone and an entire city block will have been built atop the 26-acre rail yard. Literally on top the trains will continue to run on the same tracks they are on today, but a $1.5-billion platform will keep them out of sight.
