SD9
The SD9 locomotives were built in the early 1980's and seen service in yards and did other duties as well. Not to many SD9's are left on the Norfolk Southern Roster.

SD40-2
The SD40-2 locomotive was built in the early 1970's. This locomotive was used as a helper on steep grades and even would be seen pulling freight trains. Norfolk Southern has since replaced these locomotives with the SD40E as helpers on the Pittsburgh line and other parts of the railroad. The SD40-2 locomotive has a 3,000 hp engine.

SD40E
The SD40E are rebuilt SD50 locmotives used for helper service. They have a 3,000 hp engine that was downrated from the SD50 engine. These engines have replaced the more common SD40-2 locomotives on helper service.

SD45-2
The SD45-2 was built in the early 1970's. There are currently only 6 SD45-2 locomotives on the Norfolk Southern Roster. They have a 3,000 hp engine.

SD50
The SD50 is a 3,500-horsepower (2,610 kW) diesel-electric locomotive built by General Motors Electro-Motive Division. It was introduced in May 1981 as part of EMD's "50 Series", but prototype SD50S locomotives were built from 1980; production ceased in January 1986.

SD60
The SD60 is a 3,800 horsepower (2,800 kW), 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division. Intended for heavy-duty drag freight or medium-speed freight service. It was introduced in 1984, and production ran until 1995.

SD60I
The SD60I model has a full-width short hood and features the so-called "WhisperCab" that was isolated from sound and vibration using a system of rubber gaskets. The same cab was later used on EMD's SD70I, SD75I, SD80MAC and SD90MAC locomotives. Only Conrail ordered this model, and all now belong to the Norfolk Southern Railway and CSX Transportation.

SD60M
The SD60M features a "North American safety cab" design and has a full-width short hood. Early models featured a three-piece windscreen with vertical windows (nicknamed "triclops") but later production used two windshield panes that were sloped back, and had a somewhat shorter nose.

SD70
The EMD SD70 is a series of diesel-electric locomotives produced by the Electro-Motive Division of General Motors. Production commenced in late 1992 and since then over 4000 units have been produced; most of these are the SD70M and SD70MAC models. All locomotives of this series are hood units with C-Ctrucks. Prior to the SD70ACe and SD70M-2 models, all SD70 models were delivered with the self-steering HTCR radial truck.

SD70M
The SD70M has a wide nose and a large comfort cab (officially known as
the "North American Safety Cab"), allowing crew members to ride more comfortably
inside of the locomotive than the older standard cab designs. There are two
versions of this cab on SD70Ms: the Phase I cab, which was first introduced on
the SD60M, and is standard on the SD80MAC and SD90MACs, and the Phase II cab, which is a boxier design similar to the original three-piece windscreen cab in the SD60Ms. The Phase II cab has a two-piece windscreen like the Phase I windscreen but the
design of the nose is more boxy, with a taller square midsection for more headroom.

SD70M-2
The SD70M-2 is a DC traction version of the SD70ACe, and the two models are
nearly identical in every other respect. Production commenced in 2005.It has the modified Phase II cab of the SD70ACe model. SD70M-2 models are equipped with the 16-710G3C-T2 prime mover which is rated at 4,300 horsepower (3,200 kW). They are able to generate 113,100 lbf (503 kN) of tractive effort (continuous; 163,000 lbf (730 kN) starting). Braking effort is rated at 86,850 lbf (386.3 kN)

SD70ACe
The SD70ACes are similar to the SD70MAC; however, the model has been upgraded to meet Tier-2 EPA regulations. Production commenced in 1995. SD70ACes are equipped with EMD's 16-710G3C-T2 prime mover, rated at 4,300 horsepower (3,200 kW). They are rated at 157,000 lbf (700 kN) continuous tractive effort (191,000 lbf (850 kN) starting). Braking effort is rated at 106,000 lbf (470 kN )

SD80MAC
The SD80MAC is a 5000 horsepower (3.7 MW) C-C diesel-electric locomotive. The SD80MAC uses a 20 cylinder version of EMD's 710G prime mover, and is the first diesel locomotive to use a 20-cylinder engine since the SD45/SD45-2. The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brake at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting difference between the SD80MAC and SD90MAC include: no external rear sandbox on the 90MAC, rear number boards, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although NS has removed the lights on most of their former Conrail engines.
