Re: Weight Distribution- NOT Weight Difference

When there is a dislike of the tracking of a locomotive like class K-37 on the D&S for example, has there ever been any experimenting of changing the weight distribution onto the pilot wheels or trailer wheels? There could also be changes made in the springs and linkage which will draw the frame over when the pilot wheels turn into a curve, stronger or weaker. Over age, leaf spring change with service and create a entirely different per axle distribution than was originally designed by the skill of the builder, such as Baldwin and their years of experience. I would imagine that small railroads like D&S, which has no axle scales, has never considered redistribution of more or less engine weight to different axles.
A few winters ago I was sadden to see a steam engine dead at Mt. Dora, FL because it burned up the bearing on the front pilot wheel axle on one of its few trips to Orlando. It was never repaired. From what I saw, I would judge the leaf spring over the drivers sagged by age and because of equalizing linkage, excessive engine weight was relayed onto the pilot axle bearings, causing them to overheat and be destroyed. Simple study and a little wedge blocking could have corrected the weight distribution.
Those springs that are involved in the swivel of the pilot and trailing trucks could be adjusted to improve the steering and track ability of the K-37s.
