The main cause of the Rex locomotive lope was that the distance in the siderod holes was not exactly the same as the distance between the axles. I remember someone filing the siderod holes (I think in #3, or maybe #2 and #3 holes to an oblong shape parallel to the rod to compensate. I tried it and it works.
