Straight active subway tunnel exploring action
Under Chinatown, there’s a stretch of mostly disused subway tunnel unlike any other in NYC. It is relatively poorly documented, not appearing on any publicly available subways maps.
The tracks leading to Jamaica Yard under Queens Blvd. are a complex testament to the forward thinking applied to much of the construction of the old IND route lines.
Deep in South Brooklyn, there is a 4 track subway tunnel that is very familiar to anyone who has performed contract work for the MTA.
C train in the yard The 174th street subway yard is a cavernous space under Washington Heights that is currently used to store C trains.
The 137th street subway yard is one of the few subway yards built in NYC that is entirely underground.
