Thanks for all the help, I was considering the LED idea as I had done that to some MTH passengers cars and they tuned out great... So just to clarify, instead of pulling up the track to install insulated rail joiners, I can't just add a second transformer (Z1K) to the same TIU input? Will that overload/cause problems? Is there any way to rewire without pulling up the track?
Thanks so much for your help.
