Check the wheel gauge. Often wheels are set too close together. You want, um, 1.575 inches between the "backs" of the wheels.


(There's been much argument over the proper dimension to measure, but this is easy and works.)


The other thing to check is your track work. Is it nice and flat? Are there kinks at the joints where there's a gap to catch a wheel flange? Does it suddenly change grade at a joint causing wheels to lift off the rail?


If there's a spot where it frequently derails, get your noggin on the ground and watch closely as you drive slowly over that spot and usually you can see what's happening.
