The New York Central main line between New York and Buffalo was the main railroad through Syracuse. The original line through the city involved street running, replaced in 1936 with an elevated route. NYC also had a freight belt passing north of Syracuse. In the early 1970's, expressway construction eliminated the elevated route, and passenger trains began using the freight belt. Amtrak continues to use the freight route. The passenger and freight routes separated and rejoined at East Syracuse, 4 miles east, and at Syracuse Jct. (SS2), 4 miles west. New York Central identified its towers as "Signal Stations" (SS), and these Signal Stations were usually numbered. Syracuse Jct. also was the junction with NYC's Auburn Branch, west to Rochester via Auburn and Geneva. JG was 2 miles north of Syracuse Jct. on the freight belt, and was the junction with NYC's St. Lawrence Division. The St. Lawrence Division separated into two lines at Woodard, 5 miles north of JG. The main line continued north to Massena, while a branch proceeded northwest to Oswego. Also serving Syracuse, and operating out of a separate station, was Delaware Lackawanna & Western. The DL&W line extended from Binghamton to Oswego, connecting at Binghamton, with its main line between New York and Buffalo.
