Other yards 36th–38th Street Yard The 36th–38th Street Yard, sometimes referred to as simply the 38th Street Yard, is located between Fifth and Seventh Avenues in Sunset Park, Brooklyn, adjacent to the Jackie Gleason Bus Depot and the Ninth Avenue station of the BMT West End Line. Green-Wood Cemetery lies to the north of the yard. This yard is not normally used for revenue-service train maintenance. Its primary function is to store diesel and electrically powered maintenance-of-way and other non-revenue service rolling stock. It is also used to transfer trash from garbage collector trains to trucks via platforms inside the yard just south of 37th Street. There is a control tower for the West End Line at the south end of the yard. The yard is entirely equipped with hand-operated switches. Only Fresh Pond Yard and East New York Yard share this characteristic. The Metropolitan Transportation Authority plans to enlarge, and modernize this yard to accommodate, inspect and maintain additional revenue service trains here, due to chronic overcrowding at their other existing main facilities, as many trains are stored on the BMT Fourth Avenue Line's mainline express tracks during off-peak periods. The expanded yard will also provide much-needed storage space for future Second Avenue Subway trains. Up to twelve storage tracks would be added along with power switches, with some non-revenue trains relocated to other areas. Plans to expand the yard for revenue service trains have existed since the late 1980s. This southern part of the yard used to be the center of the South Brooklyn Railway (owned by the Brooklyn Rapid Transit Company), which extended from Bush Terminal through the north part of the yard, then down Gravesend Avenue and into the Coney Island Yard. What is now the Jackie Gleason Bus Depot was formerly the site of a train inspection shed. Linden Shops Linden Shops is a track shop, where track switches and other components are assembled. It has track connections to the IRT New Lots Line and the BMT Canarsie Line, but no third rail, restricting the facility to diesel-powered trains only. There is also a track connection to the Long Island Rail Road's Bay Ridge Branch. This connection is one of two from the subway to the mainline United States rail network
