What they need to do is convert the SD70M-2's to SD70Ace's. Those non-radial HTSC trucks were never really designed for DC motors and believe me, it's next to impossible to change the top front brushes on the number 2 and number 5 motors. In my opinion, the GE Dash 9 is the best locomotive in the fleet, they need to leave that one alone. If they want to upgrade a GE product, they should upgrade the ES40DC to the ES44AC model. But like we say at work, it's not my trainset
