Well, after clearing out all the consists the other night, I haven't incurred any other electrical issues. This evening, I spent about an hour operating with no problems.
A side note: I really like the Tab-on-Car System. Currently, I have cars everywhere as I'm working Ottawa Sand. After separating the cut out due to five overweight cars, it would have been hard to keep up with which car went where. Now, I can place cars wherever I see fit and easily gathering them back up to move them out.
I guess I should get back to work sometime on the layout, but I have enjoyed operating on my own.
