The GG1 is cool. Like I said, I don't really like pantograph locos, but the engineer in my appreciates a fantastic loco design, and the styling is superb. It appears multiple times in a fiction book I'm writing now.
I ran the model some today - minus the pantographs. It is a big, very impressive model. This one has really good, glistening paint and graphics. Quite nice.
What did they sound like? This Williams model has no sound, of course, but then, probably that is pretty close to accurate. i drive a Chevy volt most days because, being electric, it makes no sound at all. I suppose the GG1 was fairly quiet?
