Loco Bill...thanks so much for the answer...I think it's just what I was looking for. Didn't even know the terminology. Will look for "wheel wipers" and see about switching the bulbs to LED's. For now, I just think I'm gonna put it together and get it on the tracks and let the passengers ride in the dark. I've been in the dark most of my 66 years and it hasn't bothered me too much.
Thanks again/Bob
