Re: ADMIN: Wheels have rolled far enough

Max, you missed the point. Reducing the TE necessary to haul the hoppers by
reducing both the starting force required, and the rolling friction once
moving, can have a significant effect on how many hoppers you can pull.
PART of the problem was the hopper TRUCKS. With replacement wheels
properly<< fitted to the truck frames (that is, with the appropriate
length of axle), the rolling resistance is dramatically reduced.

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.
