Ok wgat I did was take Rail Jointers and soldered Wire too the 3 Track I had at one time.Then WIred them too the two Yard Wire Tracks & the Turntable too,those were all splced togther to the Roundhouse Tracks and the Yard Track.But what I am trying too say if I already Had the 9 Single Tracks. With 2 Rail Jointers on each Track and had Wires Soldered too the 2 Jointers that would be 18 Total Wires.Coming from teh 9 Single Roundhosue Tracks how should I connect those to the 2 Main Wires coming from the Single Mainline Track.That is what I am asking You.Please tell me step by step info Thanks for your Reply JBAAKKO
