Amtrak now has three Phase 7 P42DCs (AMTK 174, AMTK 82, and AMTK 138). AMTK 138 is the newest repaint in the new scheme, and it along with AMTK 82 led the Zephyr westbound out of Denver. This is the first time a patched pair of Phase 7 P42DCs have led the Zephyr (or, to the best of my knowledge, any train).
