Carl, I am having trouble with my engine jumping off the tracks with one Gilbert switch with its pilot truck. Did you place the washer right above the screw head under the pilot truck or on top of the pilot truck?
A friendly suggestion........
If Carl's suggestion does not solve the problem, you might check the gauge of the offending Gilbert turnout. I have noticed that some Gilbert switches, particularly those made in the later '50s are a bit off. Gilbert trains run fine through them, but some of the newer high rail steam engines can be problematic.
