Ben,
Thanks Ben. I will try it out tonight. In question 2, I was just saying
if I ran one train around track#1, and had the switch going to track#2
(and not having the controller on, all the trains would be switched
off), would it cause a problem, or would it just be considered another
piece of track to go on.
I will let you know! Thanks again!
