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 railroad continued this practice until its merger with the Burlington Northern Railroad in 1995, and the new railroad, Burlington Northern-Santa Fe (later BNSF Railway) furthered the practice. Introduced during the Dash 8's later years were split-cooling in the radiators and electronic displays for the crews (instead of analogue gauges).
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.
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.
This line is still owned and operated to this day by the BNSF Railway under a purchase-of-service agreement with Metra. In May 1980 when Mount St. Helens erupted, the BNR owned the land around the summit of Mount St. Helens in Washington state. In the 19th century, the United States government distributed land to railroads as a way to open up ...
This version of the Dash 9 was manufactured between January and March 1995. All 125 examples of this model are owned by the Norfolk Southern Railway.. The C40-9 is the only model in the Dash 9 Series to feature the standard cab design.
All models of the Dash 7 Series are powered by a 12-cylinder or 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine carried over from the Universal Series, and have speed-based adhesion control with a multi-channel LED annunciator panel.
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.
