Construction was completed on a long segment of the Montclair Branch from East Orange to Glen Ridge and was opened to rail service on November 15, 1912. The project laid of track in addition to steel ties and stone ballast. The station has concrete crossings at Dodd Street, Arlington Avenue and Watsessing Avenue along with a new crossing of the Erie Railroad's Orange Branch just south of the station. The design of Watsessing Avenue's new station was difficult due to the limited right-of-way. While making the separation, a new trench had to be dug, which included retaining walls that prevented moving the existing track alignment to delay railroad traffic. When the station was finished, tracks were shifted to make room for a second track. The station depot was built over the railroad tracks with four concrete arches to support the building. A four-inch (10 cm) ceiling was constructed on the arches, and the station was widened to take more volume of train service.
