 Ellwood:

 What passenger cars are you running? It always helps to give as many details as you have, no matter whether you think they are factors or not in the problem.

In other words, no less than 10 FT diameter curve track, I personally have no less than 14 FT diameter on my main line for running those 33 inch long USA streamliners.

I'll echo Brian's comments. I would only add, double check your rail joints. If they are not dead on aligned both in correct curvatures (no gaps in the rail joiner) and in elevation both side to side but also linear (along the rails). If the rails are not properly supported and aligned the rail joints will "flex" as the train passes over which could add to derailment problems.

 Bad track work most likely. If these are the long streamline USAT cars, they should only be run on R3 and bigger curves. R5 and bigger is a better bet. #6 switches are usually required.

Check for dips in your track and side to side level. These cars require almost perfect track work to run well.
