I hope you all will be patient with me. Can't seem to find the answer to this online. Thinking of setting up a small L-shaped loop to loop 0-27 trolley layout. Are manual switch tracks made so they will "float", and not have to be thrown each time the trolley passes? It would be nice to have a Christmas display with this hands-off capability, so the trolley would circle each reversing loop in a different direction each time. Can this be done?
