I swapped the chips this weekend, and both locomotives drove. A EP-5 sure is funny to watch with steam sounds. I've gotten in touch with Midge and will be ordering a new chip. I'll let you know when she's running again. Thanks for your help.
@GGG, I did try the reset of options 3 and 17, and it didn't work. I may of not done it right, and my manual actually says that option 2 if for selecting ENG ID on an upgraded for the future. But at least I know a new chip will solve the problem.
