As on the Main Line, trains are powered by diesel locomotives operated push-pull, consisting of Comet or MultiLevel coaches.

This portion was opened in 1833 by the Paterson and Hudson River Railroad[2] and leased by the New York and Erie Rail Road in 1852.

[3] The rest of the line, from East Rutherford north to Glen Rock, opened in 1881 as the Bergen County Railroad.

This was caused by the abandonment of the Main Line section through downtown Passaic and construction of Interstate 80 using the old Boonton Branch right-way in Paterson.

[6] On February 21, 2007, a Bergen County Line train suffered a minor derailment after passing over an improperly repaired switch at Ridgewood Junction.

[8][4] Soon the train joins the old Erie Main Line right-of-way and crosses the Hackensack over HX Bridge, a two-track bascule draw.

Shortly after passing beneath U.S. Highway 46 the track becomes the border of Saddle Brook and Elmwood Park, once again crossing Midland Avenue.
