And Trix had a GG1.
This is coming close to the Big Boy, although at least there were a lot more actual GG1's than Big Boys. How many do we need?
The BLI one was never limited in availability, that was before they learned and they made way too many of them, so the only people who paid full price for one of those were those who had to have it on launch day, kinda like the latest smartphone, or video game, or whatever. Anyone who waited a bit got them at 50% off. Great runners and they could actually pull a full length passenger train, even one made up of older Walthers carts, without resorting to gimmicks liek traction tires, because they were all metal bodies. Used to have access to one, it was a great runner.
The Mehano ones aren;t bad either, but the single motor ones actually pull more, because they have more weight. The dual motor ones run nice, but need to be doubleheaded or else run with a shorter consist.
Of course there were probbaly millions of the Tyco ones made - if you can stand a GG1 on Alco 6-wheel trucks (with only 4 wheels in each). Hmm, freelance streamlined version of an E44, anyone?
