Good Afternoon everyone, DC Layout 10ft by 6ft. So I have changed my plan again (track plan 979 😂) but I have a problem with my wiring so I wondered if someone could help or send me a wiring diagram. Two loops main line / branch line, when a train on the mainline goes into the train maintenance depot it needs to cross the branch line track then go into the depot. However when a train is on the branch line at the same time it would hit the train going to the maintance shed. So what I need is when I change the points on the mainline I need a fail safe so the loco on the branch line only goes so far and stops. Hope this makes sense lol Deano
