Amtrak celebrated its 50th anniversary in 2021, and painted up two units (a P42DC and a Charger) in a special commemorative scheme. For five years, the P42DC has managed to elude me, but I finally caught it on this beautiful Easter Sunday. AMTK 100 and AMTK 25 lead the eastbound Zephyr through the Denver suburb of Arvada, running about 25 minutes late.
