Say hello so the SD70AH. What makes this unit different from an SD70ACe? 7,000 pounds! For a long time, various railroads have, at times, increased the weight of certain locomotives to try to increase their tractive effort. Such is the case with the SD70AH. EMD increased the thickness of the steel frame, adding the 7,000 pounds.

Interestingly, I got a picture of UP 8923 back in 2007. That was a different unit, however. At that time, UP 8923 was an SD90MAC that was waiting to be sold off. Check out the picture in the "Additional Photos" below.
