The problem was not the hoppers. It was the hard chrome plating on the
driver's tires! After that was machined off, with no other changes to
the loco, the results were as mentioned with the same cars and wheels.
At that point in time, the only semi-scale wheels available were some
NWSL Code 72 and CV "Fine Scale" if you had a hoard put away.
