I'm still not sure exactly what you want to do.... How many trains ? one for each siding? How do you select which train and line the switches? What do you want the trains to do.
PS.. I spent 6 months on one of my single track and sidings layout hooking up blocks with relays and insulated track sections. You lock your engine in forward and sit back and watch 'em go.. Worked pretty well too but soon became very boring. I suppose the challenge was hooking it up. Never could get it to work in both directions .
