Although not quite so obvious as the IC125, the GG1 was also a sleek beast back in its day. It’s also a notorious challenge for LEGO train builders. Nathaniel Brill (Shuppiluliumas) rises to the challenge with two versions of the mythical beast. Note especially the skates on the pantograph (the shiny bit up top), a very nice part use that’s been doing the train rounds for a bit*.
* As I recall we have Dave Stannard to thank for it.
