Ace posted:You could also slit a plastic drinking straw and place that over the center rail to prevent electrical contact with the loco center rail pickups. No extra rail gaps required.
Great idea! I bet you can even find them in black at a party store. You could also use electrical tape. That will leave a glue residue, but would not move. A single piece of tape could also be used to secure the straw for extra protection, by wrapping the straw and rail in the middle, between the ties.
