Edgewater Tunnel

The Edgewater Branch ran about 3.174 miles (5.108 km) through eastern Bergen County, New Jersey in the United States. Starting from the New York, Susquehanna and Western Railway's (NYSW) Undercliff rail junction at the Little Ferry Yard (in Ridgefield), it went east through the Edgewater Tunnel to Undercliff (as Edgewater was once known) to the Hudson Waterfront.

The NYSW handled passenger and freight traffic from the coal mining region in the Lackawanna Valley in and around Scranton, Pennsylvania through northern New Jersey. While it had a line running along the foot of the western slope of Hudson Palisades that terminated in Jersey City north of Marion Junction it owned no right-of-way (ROW) through Bergen Hill. The railroad paid substantial fees to both the Pennsylvania Railroad (PRR) (for passenger trains) and the Delaware, Lackawanna and Western (DL&W) (for freight service) to use their lines to terminals on the North River.

The Hudson River Railroad and Terminal Company was incorporated as a NYSW subsidiary in 1892. The NYSW developed a terminal on what had once been a coal yard for oceangoing ships along the Hudson River shore. At the time the Erie Railroad held a controlling interest in the line. In 1907, Erie Terminals Railroad took control of the Edgewater and Fort Lee Railroad which ran to the Hudson County line and connected with the New Jersey Shore Line Railroad, eventually becoming part of a Belt Line along the shore.
