The GE AC4400CW, sometimes referred as "AC44CW" is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. Similar to the Dash 9-44CW, the AC44CW uses AC traction motors instead of DC, using a separate inverter per motor. In appearance, the AC4400CW is somewhat similar to GE's more powerful locomotive, the AC6000CW.
