These three pictures were taken in July of 1974. 
NEW YORK, SUSQUEHANNA AND WESTERN
Basically a New Jersey only shortline for many years, the Susquehanna was on the verge of abandonment in the late 1970's when the line was purchased by Walter Rich. Beginning in 1980 the 'Suskie' grew steadily and then almost overnight became a large regional carrier when it temporarily assumed operation of the Delaware and Hudson. Following the sale of the D & H to CP, the 'Suskie has gradually retrenched, although very much active. Today it operates its original main line from Little Ferry, NJ to Sparta Jct., a portion of the former Lehigh and Hudson River from Sparta Jct. north to Campbell Hall, NY and also the former Lackawanna branches to Utica and Syracuse from Binghamton, NY. They have haulage rights over the southern tier ( Erie ) between Campbell Hall and Binghamton.
The photographs below are from 1974 through 1992. Beginning in Little Ferry which is the roads home terminal:
These three pictures were taken in July of 1974.

The railroad actually extended a little further east from Little Ferry and ran through the Palisades in a tunnel and had track along the Hudson River waterfront in the town of Edgewater, NJ. Here are several pictures taken on a very lucky day for me. July 7, 1980. RS-1 252 was fully painted up for the 1976 USA Bi-Centennial.
This area was abandoned by the railroad after the major customer in Edgewater closed up. The area is now filled with parking lots, stores, condominiums and a marina.
Here is 252 returning to Little Ferry passing under Highway
1&9 in North Bergen, NJ.
After returning to Little Ferry the unit went to work switching the yard.
While 252 works a cut of cars, 1802 enters the yard. Check out those boxcars and the coach in the background!
Here is some freight equipment the Susquehanna owned that has seen better days.
The
Bergen Record is the areas major newspaper and their printing plant is a
Susquehanna customer.
This caboose has a New Haven look to it, but it was built new for the Suskie in
1948. Two remain existent today
In 1981 the 'Suskie' ran their first major railfan trip. 
Both pictures in Little Ferry.
A few more pictures of the Little Ferry terminal through the years.

Through the 1980's the GP-18's remained the primary power. In 1988 the Susquehanna bought several BN SD45's and numbered them in the 3600 series. For those not familiar with the Susquehanna, units with MU capability are evenly numbered and the units are numbered based on horsepower ( except the original Alco's and the 120 above.). Three GE 4000 hp units were purchased shortly thereafter, numbered 4000, 4002, 4004.

Around 1992 the Susquehanna closed their old engine terminal.
At the new facility, E8 2402 and a former UP unit sit. 120 and 116, a genuine former Ontario & Western NW2.
Back again to July 7, 1980, here is 1800 bringing a long cut of cars from the Conrail interchange.

On the 1981 fan trip, a car derailed in Oakland, NJ and it made for quite a scene.

Butler, NJ was the end of commuter service in the old days.
Today, Butler is the site of the railroads maintenance yard. That boxcar
needs to covered up !!

When the Susquehanna expanded into upstate New York, Binghamton became the focal point of operations. Particularly when they operated the D & H in the early 1990's. CSX funded several GE B40 units which came in full Susquehanna paint. They are now in service for CSX.

Ex-LIRR 2010 Wrecked 3004 3002 in service 3636 and 4004 in the East Binghamton yard.
One of the trains operated by the Susquehanna for the D & H were trains RPPY and PYRP between Rouses Point, NY and Potomac Yard, Alexandria, VA.
Here former BN SD45 6361 leads PYRP out of the Allentown, PA yard headed
north
These trains had to reverse direction in Allentown yard as there is no direct
connection from the former CNJ down from Scranton to the former Reading west out
of the yard. The engines had to run around their train.
Train RPPY departs Allentown heading west on the former Reading. From here
the train went to Reading, PA and then down the former Reading main to
Philadelphia to reach to old B & O main. This was very similar to the old
NE-84 and NE-87 trains. They ran from Portland, Maine to Potomac yard via
the Boston & Maine, D & H, Lehigh Valley, Reading and the B &
O.
One other operation that the Susquehanna ran in the early 1990's was the freight portion of the Staten Island Rapid Transit. This was owned and operated by the B & O and the Suskie became the designated operator for a short time.
Both photos taken at Cranford Jct., NJ in 1991.
