Does anybody know what engine specs are used on Jointed Rails Dash9s and GEVOS? It's quite ridiculous that I'm forced to use eight locomotives just to get and intermodal train up to 70 mph on a level line. While AI can get a 100 car mixed freight up to the same speed with four units; two SD75Is and two SD75Ms. And what's your guys experience with these specs. Do you need less units to pull or what?
