How Subway Cars are Delivered Subway cars being delivered, refurbished, or sent out for scrapping travel through a railroad connection to the BMT West End line at 9th Avenue. Called the South Brooklyn Railway, or SBK, two diesels make up the entire railroad. Referred to as N1 and N2, these diesels are responsible for subway car movement in the Bush Terminal warehouse area. The SBK in turn, connects to a railway on the waterfront referred to as the NY Cross Harbor Railroad.
Cars travel by a barge between Greenville, NJ and Brooklyn.
The BMT Canarsie Line and IRT Livonia Avenue Line connect to a yard known as the Linden Shops, which is a fabricating facility for the system's train tracks. Work trains travel by a non-powered 3rd rail connection. This connection is essential in that it serves as an alternate connection for the BMT Eastern Division to the rest of the Subway System. Whenever the Williamsburg Bridge is closed to train traffic, subway cars going to Coney Island for maintenance must travel along the Bay Ridge Line to the piers and travel up by the SBK connection to the West End line for access to Coney Island. SBK has trackage rights on the Bay Ridge Line to complete these moves.
