I think what was impressive, to me, was the description of the drive train. The mention of six pairs of "Traction" motors.
"The Pennsylvania GG-1 locomotive is the second of the Kohs series of class American locomotives of the 20th century. This type of drive incorporates 6 pairs (12 total) of Swiss made core-less motors positioned as the traction motors were in the original prototype, rather than the twin Pittman motors used in the standard version."
In the list below the two descriptive paragraphs, it mentions two Pittman motors. This must be the features of the original release.
