NJ Transit maintains a substantial train servicing yard east of the Netcong station at Port Morris in Roxbury Township.

[8] Service to Netcong, once known as South Stanhope, began on January 16, 1854 by the Morris & Essex Railroad.

The current Netcong station was built by the Delaware, Lackawanna and Western Railroad's main line after construction of the Stanhope Cut-Off from 1901–1903 as the main station to Netcong and nearby Stanhope.

Prior to 1994, NJ Transit's service on the then-Boonton Line terminated at Netcong.

However, in late 1994, service was extended along the Norfolk Southern owned tracks to Mount Olive Township and Hackettstown, which became the permanent western terminus of the line.
