Great, got the idea. Bit late at night here to try that now!

I just got hold of an exploded parts diagram, but it shows the axle as a split axle, 2 halves connecting to the center gear, which is much larger, so apparently there is more than one version.

It matches the link I posted before where the axle was broken in two.

Hard to find information on this loco.

I can email the parts diagram if requested, and there are a few parts on the bachmann site, but they do not have the driven axle, only the axle with the chuff cam.

Greg, that sounds like the 2-4-2T tank engine, "Lyn" and the black version, which I also took apart once. They have a split axle. The original Columbia tender engine does not.
Check out the photos that "G Too" posted and compare them with mine in the subsequent posts.

Nope, not the tank engine... the "columbia" type, posting here in lower resolution.. I might be mistaken once but have been reseaching, Dave Goodson opened his box today, took out this document and scanned. This document obviously matches the loco Dave has in his possession, and matches the link provided before. So again, it appears there is more than one version of this loco, and yes, I understand that the one here in question has a different driven axle.
i have noted on my site there appears to be more than one version.

Interesting. And I'm sure there's a third version of the axle on the later chassis with the brass gears!

I have not seen that (3rd version), and because this has been out of production for some time, I would be skeptical as to it's existance. Likewise, I've never seen the single, solid axle you show for the Columbia, and unfortunately, it is not listed in the spare parts, so no way to see, but this is all I can find, TOC and I spent some time researchiing.

Pete, if you ever find an exploded parts diagram for the axle type you show, I'd love to get it. Also, anyone that wants a high resolution copy of the diagram I show above, just email me..

Greg,
There's a discussion of the various versions and dates here:
Bachmann Forum

And the parts store lists the latest chassis with a photo:



You will note the motor is upright, unlike the early versions where it is horizontal. No idea why.

Yes, I saw that, but notice the part number: 242-CH-OLD

Makes me think the vertical motor show is the original/older , and the horizontal motor, which matches what TOC has new in the box, is newer.

I think this is also similar to the 2-4-2T loco the Lyn and it's variants that had both motor orientations over time.

sure wish I had the part numbers and corresponding pix for the driving axles.. i notice that there is a driver with a brass gear for the 2-4-2T / Lyn, which looks a lot like your picture above.

In any case, I've more research to do.
