weight and therefore the electrical contact on the remaining drivers. It's
not just the Mikado frame BTW, as far as I know all the steam locomotives
are similar (although I have heard the new run of 0-6-0 is not).

drivers all contact the rail. The styrene wore away rather quickly and
caused the middle driver to lift when power was applied, which threw the
wheelsets out of alignment. I ended up replacing the cover so the middle
driver was lifted again. I'm sure that if I had put brass shims in instead
it would not have had this problem, but truthfully I didn't see any
advantage to the modification (other than cosmetic).
The best way to do this would be to somehow compensate the axles so that all
the drivers could contact the rails all the time. I don't know if that's
possible at this small scale. How does AZL do this on their Daylight loco?
