Avenue and the Harlem River north of the University Heights Bridge. The outdoor yard, which was originally constructed for the B Division, extends north from 207th Street to 215th Street. It serves as the home yard for the R179s that are used on the . There is a car wash here. The 207th Street Shop is one of two heavy overhaul shops in the New York City Subway system (the other being the Coney Island Yard in Brooklyn) and it provides for the overhaul and rebuilding of some A Division cars as well as most B Division rolling stock. The yard stores cars that are being retired or awaiting scrapping, and it also restores cars designated for the New York Transit Museum. It also contains a garbage transfer station. Formerly, the retired cars that were stored at the yard were stripped of usable parts such as seats and doors, historic memorabilia such as rollsigns, and toxic materials such as lubricants and asbestos, after which the cars were scrapped or sunk into artificial reefs. South of the yard, connecting tracks lead to the IND Eighth Avenue Line. A separate connecting track and flyover leads to the IRT Broadway–Seventh Avenue Line. A major rehabilitation project for the yard took place in 2016. Concourse Yard The Concourse Yard is located in the northern Bronx near the intersection of 205th Street and Jerome Avenue.

The two basins are divided by Goulden Avenue, and land for the eastern basin was cleared and partially excavated in anticipation of construction. The two-basin plan was abandoned in 1912, and the excavated area for the eastern basin was filled and graded. In addition to the building of the subway yard on that site, Lehman College, three high schools, a park, and several public housing developments were also built there. The yard was built at a depressed grade, 18 feet below grade, to allow for the yard to be roofed over to allow for the construction of buildings. The tracks were spaced apart to permit the placing of stable foundations and columns to support buildings that can could be erected atop the proposed roof of the yard. The yard was originally bounded by Navy Avenue (now
