I have a 12 foot long track that contains a k-line plymouth switcher and a single hopper car. The operation is controlled by a Pocono Mountain Line auto reverse board. At one end of the line I have a gargraves 0-42 turnout. In order to introduce some variation to the route I was wondering if there was a way to introduce a random selection to the route this small train travels. I would like to have the route selection alter between taking the divergent route or proceeding straight. Is there a relay of come kind that would accomplish the desired effect?
