Mike,

Thanks much, will check out your suggestions.

Please help. I would like to lay long single track & have a turnaround at each end. This would be a lot lower in cost than running down one track & back up the other. Anyhow, if a "circle of track with a switch", was at each end of the single track. Would there be a current/polarity problem when an engine/train went around the circle , through the switch and reentered the single track? Is this correct? Will it work OK, not causing current/polarityproblems? Thanks much.

Ed
