In all my looong life "playing" with trains, I'd never had to re-gauge a wheel set.....Until I purchased a B'mann 2-8-4. The pilot truck kept jumping off the rails on the exit to the turnout leaving the yard. Literally thousands of wheel sets/trucks have gone through that track with nary a whimper. So I figured there was something wrong with that pilot truck (Brilliant..!! 
). I took it off, and checked the gauge with my micrometer, and compared it to the gauge of another wheel set. Yup...It was a tad on the narrow side. I spread the wheels on the axle just a bit...and...It worked..!! So there is something to having a gauge around when checking track/tracking problems....
In your case, I suspect the track itself, and while additional weight might "cure" the symptoms, the cause will still be there....
