 The Broadway and Seventh Avenue Railroad opened a line from Lower Manhattan to Central Park in 1864.However, south of Union Square, tracks were not allowed in Broadway due to local opposition.Thus the route began in the trackage west of City Hall, jointly owned by the Sixth Avenue Railroad and Eighth Avenue Railroad, and used the one-way pair of Church Street and West Broadway to Canal Street and Greene Street and Wooster Street to 8th Street, north of which both directions used University Place to Union Square.
