Somewhere in Manhattan's trendy Chelsea is this office building, which just so happens to have a subway car in it.
The discovery was made by the excellent ScoutingNY, which points out the subway car is actually more of a replica than a real car. ScoutingNY also did some research and found out the car used to serve as the offices of B-Train Films, though they've since moved to a new location.
