18545RE: [z_scale] Re: Recommended track gradient
- Jan 1, 2004I think if you read back a bit, you will find that the 060 drivers were the
same diameter, there is more vertical slop in the center driver journal.
There was a discussion about shimming the center driver journal. If I
remember correctly, the center driver lifted in reverse, and pressed down in
forward (this may be backwards)... This makes sense since the drive to the
gear on the driver is pushed in different directions for the different
I think this discussion centered on either loss of electrical contact from
the lifted driver, or loss of traction.
I guess someone out there could measure the drivers on an 060 marklin loco
to confirm this.
P.s. thinking more, I seem to remember someone posted a movie clip that
showed the center driver moving "up".

I don't think the middle wheels "lift" on 0-6-0 or other steam locos so much
as they are intentionally made a millimeter or two smaller in diameter so
they do not contact the track. This is so they can get around the 145mm
curves without derailing.
