Anyone else have this situation. I have two Lionel 2-8-4s Jr. Berks. Erie number 3338 and Pennsylvania 2356. The pennys will travel the layout thur 027, 042 curves and 027, and 031 switches for hours. Now the Erie will trip and fall all over itself all over the layout, at times. Its can run fine for 10 minutes then it decides it does not like a 027 switch or curve and can either jump one drive wheel off the track or the next pass through the same switch or curve it will roll over and play dead at the same spot. The Erie is the only engine I have that I can run on the layout and it will tell me when something is out of line or not level. I have compared the two engines and the Penns drive wheel will flex independent of each other where the Erie is all ridged.
