... Agreed, pivoting from the
two inner trucks would reduce the overhang. There are two constraints
affecting this design decision: I would like to have the three-wheel trucks
on the “inside”, to better resemble the prototype; and, the motorized trucks
have the rotation pin protruding from them. Covering it the pin up would
make for a very tall set of wheels, so I opted to use that pin as the pivot
point. Another option would be a two-stage articulation resembling that on
Bruce’s recent Schnabel car - I will have to look into this. I think this
would add some height to the wheel assemblies as well.

I wonder if it might be possible to pivot where the two trucks join together.
We could have an opening for the pin on the motor trucks to move around in, like
you have done with the 3-axle trucks. And instead of the half-pin currently
used, use a longer pin that is connected to the chassis. Maybe I will
experiment a little using the GG-1 model that I’ve built...
