Here is a short video of conventional control trains running on a single track in opposite direction with 1 passing siding. The basic way it works is with four blocks that power a coil on a relay and it shuts off the incoming trains power and energizes the waiting train, it keeps doing this until the train enters the main line. It is done with 4 relays and each train has its own power supply

Nice Job...
any chance of you posting the wiring diagram ?
Diagram I labelled on the wires, that is what all the numbers are. I also installed toggle switch to have 1 train run continuously
Very nice Todd,you mastered the basic circuit. What you may want to add is a timing circuit where there is a delay between the one that stops and the one that follows in the opposite direction. Also you may wish to install a soft start circuit. This takes a bunch of relays and a timer but it adds to realistic automation.I cant make out your schematic to well but I do the basic circuit also with 3 DPDT relays. I then add the circuits described. This type timer can be used to delay the transition. When the passing siding is occupied by both trains (2 block detection relays in series) the timer is tripped.

Todd:
Neat and reminds me of the Automatic Train Control layouts shown in post-war instruction manuals which didn’t use relays.
