The Edgewater Branch was a branch of the New York, Susquehanna and Western Railway (NYS&W) that ran about 3.174 miles (5.108 km) through eastern Bergen County, New Jersey in the United States. Starting from a rail junction at the Little Ferry Yard (in Ridgefield),[1] it went east through the Edgewater Tunnel to Undercliff (as Edgewater was once known) to the Hudson Waterfront.
