Lewes Trains:
A suggestion. Your track plan will allow ONE reversing path from the outside loop to the inner figure eight, but not a return reversal (unless your back-up through the topmost switch. Consider adding another crossing path so that a train could be "re-reversed" without a back-up maneuver. That would enable continuous running AND direction changes.
Carry on, valiantly ...
