Not sure where the problem in yours arises, but my Omnicon 2-8-0 has no such problem; I've experimented with weighting a testcar (flat with at least five pounds worth of weights) on my test track and it walks away with it. If I had sufficient mainline, I'd judgethat is two dozen typical S scale freight cars. And it might pull even more--but I can't imagine ever needing that much tractive effort.Now on the other hand, my OVL RDG camelback 2-8-0 managed to slip the flexible shaft between motor and gearbox with hardly half that weight; I found the flexible tubing was so soft that it tended to deteriorate over time (after all, it is going on thirty years since these were made). I didn't have any replacement tubing on hand (all is just right for most O scale applications, which means too large for S scale), and the spacing between the two really doesn't permit something like a NWSL or even Hobbytown shaft coupling arrangement. I finally cleaned the tubing as best I could and very carefully (so as not to get ACC into motor or gear bearings) used Goo and ACC at each end, let it cure overnight, and it now seems to work all right--although I have been careful not to overtax the drawbar on it until I can find a replacement for the tubing.One thing I'm sure you've eliminated in checking yours out is that lubricants can creep into the ends of flexible tubing on either the motor or gearbox shafts or both, so if there is slippage I always clean them carefully before attempting any fix.

It has had a hard knock life with the tender swapped out, masquerading as a poor NYC loco now. For some reason the plastic coupling frequently slips on the motor shaft, but not the tower input shaft. I don’t know why because they the same situation. I tried but could not get the coupling to slip on the tower shaft. My fix has been ongoing for many years now in various forms from tapping the plastic coupling to brass tube and nuts soldered in place. This latest version is solid round brass stock drilled out to the O D of the plastic coupling. My new lathe made it all fun! (:->) I am going to say the wall thickness is about .040 when I am done. Drill have tap the whole thing for 2) 0-80 screws on shaft center - directly across from each other. Crank it all up tight for a slip free operation.
