Tony Fernandez General This is actually a SD9043MAC, a 4300 hp locomotive that was intended for conversion to 6000 hp once the concept proved itself. The 6000 hp SD90MAC concept failed; so the 9043 units remained at 4300 hp. Many have since been sold to Norfolk Southern. 3/28/2018 2:04:13 PM
Tony Fernandez General This unit is actually a 4300 hp SD9043MAC. It was known as a "convertible" since once the 6000hp SD90MAC engine proved itself, the 9043 model's engines were to be swapped out and a 6000hp prime mover installed. Many of the UP's SD9043MACs have since been sold to the Norfolk Southern in the past few years. 3/28/2018 2:10:22 PM
