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!
-Jordan
