A railroad tower with the telegraph call letters "PJ" was present on the Greenwood Lake side of the station.

[4] The station opened with the construction of the Montclair Railway, a subsidiary of the New York and Oswego Midland Railroad, on January 1, 1873.

The New York and Oswego Midland had finished their tracks at the site by April 1871, with further extension westward soon following.

[5] Service on the Midland side began on May 1, 1872, with a stretch from Jersey City to Middletown, New York.

[6] At the beginning, Pompton Junction had six trains per day, making the 27.5 miles (44.3 km), 1 hour, 32 minute trip to Jersey City.

[10] Pompton Junction received national media coverage in June 1874 after the railroad suffered a series of thefts at the station.

[11] Murphy heard the conversation and alerted High, who retreated to the nearby road but Anderson, shooting from the second story, hit him in the chest.

[11] Murphy, who was not a police officer, then detained and arrested Anderson, along with Devore and colleague John Titus, for the shooting and the warrants they had come with, bringing them back to Paterson to face charges.

The Erie Railroad, which had taken over the Susquehanna, helped promote the fact that at Pompton Junction a person could go fishing and swimming, along with excellent views of the Wanaque Valley.

[16] In April 1893, John Titus, one of the three charged in the 1874 theft ring at Pompton Junction, was killed in the Woodside section of Newark.

Titus, who was working as an engineer for the New York and Greenwood Lake Railway, primarily in the shop at Pompton Junction, died when a flat car fell off the jacks and crushed him.

All municipalities involved felt that the Pompton Junction facilities were inadequate for use as inclement weather would make things worse for commuters.

[22] The communities would reconvene in February 1917,[23] and within days, the Erie put in new walkways and bridges for passengers to use to access the Pompton Junction station.

[27] The Public Utilities Commission gave the Erie permission to eliminate Pompton Junction's railroad structures.
