of the IND Fulton Street Line in 1956, the IND "recaptured" the trackage rights of the BMT Fulton Street Line, connecting Hudson Street–80th Street to Grant Avenue. The IND Rockaway Line was formed from the purchase of some trackage from the Long Island Rail Road's Rockaway Park Branch and Far Rockaway Branch in 1955. At Wilson Avenue, the southbound track is above ground while the northbound one is at-grade. However, the land directly adjacent to the subway station makes the lower level northbound track look as though it is underground, and the upper level southbound track look at-grade.
