Sorry, but given the limited number of switches and O72 ovals, I'm not coming up with much. There aren't enough switches to make a double crossover, so that means that once you go from one oval to the other you can't go back without backing up or at least reversing the engine. It's the same with only 1 reversing loop. If you're running diesels that's not so bad, but steamers will be more difficult.
