Ok , so mountians need to dry a bit more. So, my next idea....lol. all ideas, and no results. Baised on T man saying I vould get a spur under the town, I may have room for 2 072 switches and another line. If I had vommand controll or more room I wanted to do 2 opposing trains , parking one while the other made the loop, then the next one starting. I can do this manually, but it would ve harder as I would need lights and signals to tell me whats where under the town. So this idea is scrapped. What I may do , os run 2 trains the same direction. So one enters the tunnel, and stops on one track and the other train starts and comes out the other side. I need to work out the details for automatic switching. So , I am toying with some insulated tracks. When one train hits the sidding it stops on a non powered track. When the next train pulls in, it powers that track starting it off. Then the train that pulls in hits it non powered onsulated track stoping it. I may use the switches to power the track, or a seprate insulated track at the beginning of each line. Ill play with it this week. Just can not remember stopping distances and how the switches would power the track. It can ve done old school, and i will try it. depending on the room. Unfortunately, I only have one set of switches, so this will cut out the switching between tracks untill I find more cheap 072 switches.
