I think I have read about all the threads on this forum about these switches but I can't seem to get rid of the sparks and short circuits when my engines (both diesel and steam) go over these switches a slow speed (3-5 mph). The switches are Scaletrax 031 and I have about five of these doing the same thing - as you can see by the pictures attached I have made some modifications so to return them at this point is not an option. Most seem to work correctly in one direction and usually the straight option of the switch.
This is my first experience with trains and the Scaletrax switches so don't be too critical - any advice would be appreciated.
