I have a loft layout that is running on DCC, and have three tracks that enter a tunnel, go around the end of the loft, then emerge out the other side, again through tunnels, does any one know if it would be possible to add passing loops so that a train would enter the tunnel, go onto the passing loop, trigger a switch to change the points at both ends of the loop, therefore cutting the power supply to that loop, and allowing a train waiting on the ajasent track to exit the loop, this train would then do a full circuit, again enter the loop and repeat the operation allowing the original train to run, i do not want to use reed switches as this would require fitting magnets to the locos, if this could be done the operating possibilities could be expanded. any ideas would be gratefully received.
