The original question/comment was about the ECW trucks. These are made of
styrene and when metal wheel sets were used, the metal axle wore out the
sideframe cones. Now this was awhile ago, before Reboxx introduced their
truck tool. The original sideframes may not have had true cones which
exasperated the problem.
