There can be differences in the truck equalization under weight transfer, there can be differences in how gently the controls can ease the power up to just short of slipping, there can be differences in how much the controls let a slip run away and how they ease back out of a slip. All of these would be keenly observed by an engineer but none of them are to do with being loco hauled or MU. He just notices the big visual of a given loco or MU handling better, not the little visual of which printed circuit board type is in the locker. Even an MU's spreading out of the motors would be a tradeoff, multiple axles slipping would be harder to notice and harder to adjust for.In industry the operators are always very aware of differences in machinery performance, they are not always as certain about the actual underlying reasons why however. That's what design engineers are supposed to figure out. Bill |
