Maybe add GP60M A an B units for the raton pass raton pass route. paints could be ATSF paints an ATSF/BNSF and BNSF H2 an H3 paints for the loco. maybe have autorack come with it or hoppers.
The Eyein12 GP60Ms are very good and can be found here - http://eyein12.blogspot.com/ There a bit of a ways down, and called the Remastered GP60M or something like that.
GP60Ms? Heck Yeah! I also want ATSF and BNSF GP60Bs and Blue/Yellow Warbonnet Spartan Cab GP60s. Maybe we could get a patched version.
