DC locomotives, which remain widely used, are valued for their lower prices, but are widely considered to be less reliable than their AC, or alternating current, counterparts.
This new locomotive, which uses four drive motors instead of six, has fewer parts and is designed for better reliability. Simonelli said that means a fleet of 600 ES44C4 AC locomotives could replace up to 800 older DC locomotives.
Chris Roberts, BNSF vice president of mechanical and value engineering, said “we are putting these locomotives through rigorous testing to determine the benefits of this new AC alternative, and the early results have been positive.”

Prakash--The AC44 (and current successor ES44AC) uses the same traction motors as the AC60. So the same "simple math" you used to derive that the ES44C4 gave 3000hp (two thirds of 4400 equals approximately 3000) ought to give that the ES44C4 gives 4000 hp. You're doing this the right way-- simple math is the way to try to understand things! -- but missing one piece of data!
