HELP! Im relatively new to mod trains and am developing my first N gauge layout. It is set up on a table appx. 40" x 84". I have used several of the ez track turnouts and when i use the engine with one or two other cars everything works fine. However when i add additional cars, (even 1 or 2 more) about 1/2 the time, going through the turnouts they derail. My track looks straight and the switch plates (?)seem to 'mate' with the track and running the cars through the turnouts with no power and me simply pushing them doesnt show any 'rough spots' that would could cause the derail. I hope this makes some sense..I sure could use a suggestion. Oh, this problem is not isolated to just one of the turnouts. Thinking that the little n gauge cars are simply too light, I even taped a nickle to one thinging that might 'hold it down'. Maybe helped a little, but not much. Thanks so much for reading this. mike
