The new alignment at first crosses the New Jersey Midland Railroad (NYS&W) at grade.

• The Lehigh Valley Railroad constructs its freight terminal on the south side of the Morris canal basin at South Cove, adjacent to the Central Railroad of New Jersey terminal. The LVRR reaches its new terminal over CNJ tracks on a five-year lease.

• The Lehigh Valley Railroad constructs the Edgewater Railway, on the north side of the Morris Canal basin.

• The Pennsylvania Railroad (PRR), rebuilds the passenger ferry terminal to replace the old terminal which was partially destroyed by fire. The new terminal is raised 15–20 ft (4.6–6.1 m) above the old level to accommodate new elevated rails that eliminate grade crossings in the city.^[3]

• The Lehigh Valley Railroad opens its bridge across Newark Bay. The LVRR connects with the National Docks Railway east of the bridge in order to reach the LVRR terminal.

• May 15: The New York, Susquehanna and Western Railway Edgewater Tunnel through the Palisades opened to freight traffic.

• The Erie Railroad trains shift to Hoboken Terminal, as the company merges with the Lackawanna Railroad.

Erie trains began moving to Hoboken in Oct 1956 for off peak and weekend trains. Peak hour trains began using Hoboken on March 25, 1957 with the exception of Nyack and NYS&W trains which continued to use the few remaining tracks in Jersey City. NYS&W trains were later discontinued and Nyack trains used a backup move to reach Hoboken until they were discontinued in 1966.

• With the Aldene Plan, Communipaw Terminal, the last Jersey City terminal closes. Lehigh Valley trains now terminate at Newark Penn Station, as do Reading Railroad trains. CNJ Trains run over LV from Roselle Park, NJ to Newark, NJ then on the PRR and terminate at Newark Penn Station, and use a small yard in Harrison. It was not until the late 1990s, when the midtown direct service was instituted, that NJ TRANSIT ran a service of some Raritan Valley trains to Hoboken (Penn Sta. New York).

NY Waterway re-institutes ferry service across the Hudson.

A short partially elevated track, known as the Marion Running Track, is built to connect the Passaic and Harsimus Line towards Kearny with the Northern Branch. This provided the Northern Branch with a direct connection to other lines heading west and south at Marion Junction.

Conrail Shared Assets Operations created. CSX River line is shifted to the re-newed Northern Running track to North Bergen Yard.
