Reply to "How difficult is it to convert trucks to use roller bearings?"

Is axle loading actually an important factor in the operation of our models? Suppose your 4-axle diesel weighs five pounds, then the weight carried by each of the eight journals is only 0.625 pound, or about 10 oz; and if it is a 6-axle diesel, then only 0.416 pound, or 6.6 oz. My F units are fitted with brass trucks and brass journals and seem to run perfectly well with just a drop of oil from time to time. I kind of have the feeling that ball bearings have a big "wow" factor, but may not be that significant an improvement for operation. But I could very well be wrong.
