BLI HO Scale C&O T-1 2-10-4

I have a BLI T-1 that has so far had a decoder replaced, it then tore a tooth off a gear, I obtained the spare gears along with a traction tire less rear driver set, now the loco derails on the club layouts 36" radius curves, and large radius Peco turnouts but only when on a right hand curve, I increased the spring length in the front driver set without change. Prior to fitting the new rear driver set, the traction tire wheels had shed their traction tires and the loco performed flawlessly untill the gear tooth sheared off, all wheel sets match the NMRA Gauge.

Any suggestions welcome.

On a flat surface, are all of the wheels touching the ground? What if you rotate the wheels a quarter turn, are they still touching the ground? It sounds like one of the wheels isn't quartered properly, and it's causing problems when it's slightly higher. That's my guess. Personally, I hate working on steam engines because of stuff like this, but good luck on fixing it!

Thanks for your input, all seems level and there are only certain curves it has problems with, slight dips in the rails are the suspect, but it even has one area where it walks off the track on a straight, it was OK before fitting the new traction tire less drivers to the rear, I guess attention needs to go towards track problems, maybe anything less than a twenty foot radius is a problem.
