Eastern Railroad Discussion > SD70AH?Date: 03/01/15 18:46 SD70AH? Author: dharris Noticed that this new EMD I shot at MP116 near Harrisburg was designated SD70AH instead of SD70Ace. What's the difference?

The power desk may just see them as a 4,300hp road engine deployable as needed. Say one engine has an issue, this unit may have subbed in. Then it gets interchanged to another railroad, and voila it roams the system. Posted from iPhone Date: 03/03/15 06:07 Re: SD70AH? Author: redneckrailfan thegoonshow Wrote:

UP adopted the heavy concept in 2013 and all new EMD's and GE's have been delivered to the railroad as such since then. Bryan Jones Brooks, KY Bryan's Train Photos Date: 03/03/15 07:18 Re: SD70AH? Author: CSXT_8437 Are they comparable as far as tractive effort with the GE heavy units?
