When you wired the motors in series, you created an electrical version of a regular differential between the front and rear truck.... Like most if not all Williams/WBB locomotives, it's geared to far too high. Rewiring the motors from parallel to series was easy. ... Wheel slippage was audible.
I do that to all my WBB two-motor locos and it makes a big difference - they run much better. Electrically it really is not that much more "differential" than with the motors as originally wired, and certainly not as bad as a standard 1960s mechanilcal car differential was, with that much bias to one side. I've never had any traction issues that way and its the only way I will run a two-motor WBB loco now.When you wired the motors in series, you created an electrical version of a regular differential between the front and rear truck.
Mona Lisa Vito : The '64 Skylark had a regular differential, which, anyone who's been stuck in the mud in Alabama knows, you step on the gas, one tire spins, the other tire does nothing.
I would love to see a version of this with the side rod trucks. Nice industrial look to it....I tried to find out if any of our local roads or industries had 70 tonners but only found the NYC had a few. Trouble is they were early versions with center cabs and the superstructure was quite different from the end cabs. Otherwise I would have tried to splice a couple of these together to make one.

I'm not sure. The handrails are plastic, but they are somewhat flexible, not brittle. I was able to bend them enough to open it up without breaking them.Does this one have the flimsy plastic handrails that were featured on the 44-Ton model? That is my major complaint with that one, it's almost impossible to remove the handrails to open it up without breaking at least one or two.
That is also the case with the 70-tonner. The railings on my 70-tonner were flexible enough to not break, which isn't to say that they won't in the future. Then again, maybe they heard the complaints and used a more pliable plastic this time around.The problem with the 44-ton model is you have to extract them from the holes in the frame and shell to get the shell off, that's when the breakage occurs.
