New here; can I run a second track using my digital command control center?

 I am wanting to put a train in one of my Christmas displays. The problem that I am having is space since it will be built to put on an 11'9" x 24" counter top and I was thinking about building it out of ¾" plywood and sectioned for easy storage. I want to put an oval on each end with either two rails in the back or one rail in the back and one in the front. I understand that the ovals will have to cantilever to accommodate the necessary radius. Any ideas would be welcome!!
