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...
