Thanks guys! There will definitely be more to come - more modern GEs, too. The plan is to just repaint the units that will not be scrapped in 5-10 years. So most GP38s, GP50s, SD40s, & SD45s will be left with the SPSF logo, but there will be some that will be changed - just depends on the life of the unit. All widecabs like C44-9s, AC4400s, and AC6000s will definitely roll over to the new scheme. Should make for an interesting year on the railroad!!
Edit - nope, no Espee lettering, just the Santa Fe all the way.
