The ET44AC (Evolution Series Tier 4, 4,400 hp, AC traction) replaces the ES44AC model. These locomotives have been ordered by most of the Class I railroads in North America, including Union Pacific, CSX Transportation, Norfolk Southern and Canadian National Railway. BNSF Railway will be receiving similar ET44C4 locomotives, which have no traction motor on the middle axle of each truck. CSX designates their ET44ACs as ET44AH, due to their locomotives being heavy-ballasted. |
