I decided to see if the trucks from the new Bachmann 70-ton 3-truck Climax are interchangeable with the
Bachmann Class B 2-truck Climax. Good news ! They are. They simply snap off just like the Class B. The fiddly trick is to interchange/swap out the drive shafts that are different lengths because of distance from the differential and truck spacing. I think now I'll look into the differential itself and find one more gear to get my Class B running again. It looks promising. I'll keep you posted.

After replacing all the parts below the frame of my 2-truck Climax with new parts from the 3-truck Climax (from truck to truck and all parts between) it still won't go. Sooo.....
I've completely disassembled the 3-truck Climax and have what appears to be the "transmission". It's a complete self-contained unit that 'clips' to the worm-gear of the electric motor transferring energy to the side-rides and drive-shaft. After studying the exploded view of the Class-B 2-truck Climax, they appear to be the same. Now all I have to do is build up enough courage to disassemble my 2-truck Climax and swap out the transmission. I don't expect to reassemble my 3-truck Climax anytime soon.
Wish me luck.
That is what many call, Model Railroading. Great job.

I'll try some pics again...
First is the Class B Climax and its parts list/schematic with the transmission from the 3-truck Climax.

Next if the same thing but with parts list/schematic of the 3-truck Climax. Note orientation

Hopefully the next time I update this project, I'll have the Class B Climax disassembled.
And now for another project involving matchsticks and bamboo skewers...

...and the backside (no pun intended)...

...and finally, the interior of the 2nd floor.
