The Bergen County Line is a branch off of the New Jersey Transit Main Line line serving communities to the east of the Main Line. The Bergen County Line splits off the Main Line just west of the Secaucus Junction transfer station in the New Jersey Meadowlands and then makes station stops in:

• Rutherford
• Garfield
• Plauderville (Garfield near Saddle Brook and Elmwood Park)
• Broadway, Fair Lawn
• Radburn, Fair Lawn
• Glen Rock (Boro Hall)

Just north of Glen Rock, the line re-joins the Main Line to make the next station stop in Ridgewood. Like the rest of the Main Line, the equipment used on this line is diesel equipment operated in a push (towards Hoboken)/pull (towards Suffern, New York) fashion. Trains are stored overnight in Suffern.
