Hi Jordan

Definitely recognisable as the GG1

48 studs is long - the same length as my GE ES44AC which runs OK through curves. The only ‘problem’ will be clearance for the centre overhang. Mounting the pivots at the end, the centre of the body the centre will step out quite a way. Have you tried moving the pivots more towards the centre of the loco?

Chris,

Thank you very much for your comments and insight. 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.

Another reader commented that the pantographs are rather small compared to those on the real GG1, which I agree with. Bob Hayes’ very well done GG1 on Brickshelf has a more realistic example. I have yet to find a similar design within LDD, though.

Thanks again for your design comments and suggestions!

(...) 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, (...)
