In 1994, GE delivered the first AC4400CW locomotive, their answer to EMD's successful SD70MAC. Nearly 10 years later, the AC4400CW has become one of the most successful locomotives in the history of North American railroading. The AC4400CW is operated by railroads from East to West and Canada to Mexico. Union Pacific's large fleet of AC4400CW locomotives, with hundreds of locomotives on the roster, is full of variation. Some of UP's locomotives have come through mergers with Southern Pacific and Chicago & North Western

 The main spotting feature for the AC4400CW, when compared to the similar C44-9W is the large Inverter Cabinet behind the helper's side of the cab (conductor/brakeman's side).
