I now it's been announced but I just saw it on Kato's site. Say what you want about Kato's policies, they appear to be addressing some of the wants of N scalers.
Along with the GS-4's pulling numbers, the GG1 is going to be able to pull a 15 car train up a 4% grade. I don't know if that'll be like the GS-4 where only 11-12 cars are actually on the grade like in the video, but certainly something that has been a problem for more than a few years now.
Hopefully it's back to the mid-west after the BL.
