Locomotive, Diesel, GE AC4400CW

History: The GE AC4400CW (also known as the AC44CW) is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is like the Dash 9-44CW, but features AC traction motors instead of DC, with a separate inverter per motor. In appearance, the AC4400CW is similar to GE's more powerful locomotive, the AC6000CW.

A relatively high-powered locomotive, the AC4400CW is "the most successful present day locomotive." Over the 11 years in which it was produced, GE constructed 2,834 examples for North American railroads. In 2005, all Class I freight railroads except Norfolk Southern and Canadian National owned at least one AC4400CW. As a result of more stringent emissions requirements that came into effect on January of that year, GE no longer offers the AC4400CW, replacing it with the ES44AC.

Railroad/Company: GE Transportation, formerly known as GE Rail, is a division of General Electric. The organization manufactures equipment for the railroad, marine, mining, drilling and energy generation industries. It is headquartered in Chicago, Illinois while their main manufacturing facility is located in Fort Worth, Texas.
