Question: I would like to run My G scale trains around the perimeter of my living room, above the door ways. My initial plans was to mount the track on a 10 inch wide piece of Pine with adequate support. Now while looking at the room, I would now like to run 2 simultaneous G scale tracks around the top perimeter of the room.. So here is the question : What width Pine would be adequate to undertake such endeavor? I know this answer probably revolve around the length of the trains to be used etc etc etc.... I will be using the basic bachmann 4-6-0 PRR steam engine with the standard passenger cars that came with this set. Any help would be appreciated. Should I just be happy with the one loop of track in the room and count my blessings that I am able to do just that. Thanx for your anticipated cooperation in this matter..
