In contrast, the New York City Trransit Authority still has rail connections to the LIRR and the New York and Atlantic via tracks running west from the portal of the “D” West End Line’s connection to the “N” and “R” in the Brookly Fourth Avenue Subway, approximately 39th Street and Fifht Avenue. These tracks then connect with Bush Terminal which is largely street-running but with railroad clearances, and then to both the LIRR (NY and Atlantic) and Cross Harbor. The connecting tracks are theoretically owned by the South Brooklyn Railroad which stil the terminating carrier for new car deliveries, all by rail or rail-car-float-rail, to the Transit Authority. The tracks are also useful when the overall MTA wants to run speed tests on subway equipment on the tracks of the LIRR (compatable third rail and power, slightly higher car floors and platforms), which occurs now and then. An LIRR caboose is now part of the Transit Musuem’s collection and was transferred over these tracks. The SBRY still retains its reporting marks, but as far as I know, the Transit Authority is its last and only customer as well as its owner.
