One of the differences between an ES44AC and an ES44C4 is the air cylinders and linkages on the truck sideframes of the ES44C4; these are part of the traction control system. Every time a variation in grade, traction, or wheel slip occurs, the computer adjusts the pressure in these cylinders to maintain sufficient adhesion, by varying the ...
The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. [1] This option was specified by Canadian Pacific Railway, Cartier Railway, CSX for their units 201-599, Ferromex, Ferrosur, and Kansas City Southern Railway.

The design of the Dash 8 Series is based upon that of the Dash 7 Series. The biggest changes introduced during the production of the Dash 8 Series were the first use of a microprocessor-equipped engine control unit in a diesel locomotive, and the adoption of a modular system in the construction of the vehicle body.

Like that earlier Series, it has a microprocessor-equipped engine control unit, and a modular system of construction of the vehicle body. All models of the Dash 9 Series are powered by a 16-cylinder, turbocharged , GE 7FDL 4-stroke diesel engine, with electronic fuel injection and split cooling.
The GE AC44C6M is an AC-traction 4,400-horsepower (3,300 kW) diesel locomotive, rebuilt from GE Transportation Dash 9 locomotives. AC44C6M rebuilds have been done by GE (now Wabtec), American Motive Power, Inc., and Norfolk Southern Railway's Juniata and Roanoke Shops, starting in September 2015.
