The current Glen Ridge, Bloomfield and Watsessing stations along the Montclair branch were all built in 1912 during a grade separation program by the Delaware, Lackawanna and Western Railroad. During New Jersey Transit's running of the line, two stations between Watsessing and Newark Broad Street were closed due to low ridership—the Roseville Avenue station in Newark, at the junction with the Morristown Line on September 16, 1984, and Ampere station in East Orange on April 7, 1991. The word "Watsessing" is a Native American term that translates to "mouth of the creek".
