Martin, I would hope so. I have 2 MTH 2-8-0 Railking steamers, 1 keeps derailing and the other has no problems. A wheel gauge would (hopefully) rule out any problems with the gauge of the wheels.
I know the NMRA gauge ain't cuttin it for 3-rail wheels, the distance between the back of the wheels won't even fit in the gauge.
The one 2-8-0 that keeps jumping off the track did find a problem in my trackwork that has been there for years (but not discovered by any other engine). I had a slight dip in a curve and had to insert a popsicle stick under the ties to level it (after removing a foot of ballast).
I think 3 railers would care. I have had to adjust pilot trucks on some of my post war Lionel steamers because they would derail on curves because they were out of gauge. Once put back in gauge, they ran with out any problems.
