I am the guy who did the no-no! I treated my Bachman 0-6-0 engine with WD-40 and cleaned the track with denatured alcohol because the engine wouldn't run. After, according to my peers, I did the no-no, it ran again but the sparks were flying. Well, the sparks have stopped and the engine is running fine now. But here's the good one for you---- I have to nudge the engine just about every time I start it. After it gets going, it will go and go and go. No problem. Sometimes when I stop it, it doesn't need a nudge again to get started; but then again it does. Now get this! This is only when I run the train counter clockwise on a simple round Bachman EZ track. Now picture this. I take the engine and caboose off and reverse them to let the train run clockwise. Guess what? No problem. No nudges needed. Time and time again after many trial stops, the little engine starts up just fine without any help. Why?
