Now that I have a train table built, I've thrown what I have of FasTrack on it to run trains until I can get my hands on the Atlas track I need for my layout plan. Of that track used in the temporary layout is manual O36 switches. The last axle on the tender of my K-Line Big Boy shorts out in the frog area when I am backing over them, unless I go at a higher speed, then I just get a spark. It has made switching rather difficult. The wheels on the axle have no flanges, and are narrow so that it can take O27 curves. I was surprised it happened. I guess I had just assumed that they were plastic like MTH does on their blind wheels used on their diesels, but K-Line used metal.
Has anyone had this happen, and what did you do to solve the problem?
