AMTK 174 (Phase 7) and AMTK 161 (Phase 1 Heritage) lead the eastbound California Zephyr at Blue Mountain Road. The interesting thing, however, is that this is actually yesterday's #6. Extremely high winds the day before stopped Amtrak at Fraser. And there it sat for approximately 22 hours! Here, the train is 21 hours late.
The Phase 7 scheme on AMTK 174 is indeed the "go-forward" scheme for Amtrak. Amtrak has announced that as both power and passenger cars require maintenance, Amtrak will slowly be repainting them in the Phase 7 scheme.
