PPCX 800588 (Northern Sky Charters) hitched a ride on the back of the morning Zephyr that came into Denver's Union Station. This colorful observation/dome/sleeper was built by ACF in 1955 as Union Pacific 9003. Assigned to “City of Los Angeles.” It was sold to Auto-Train in 1973 and then later sold to a private owner who rebuilt and redecorated the car. The amenities include one master bedroom, three double bedrooms, three showers, kitchen, full meal service, observation lounge with rear-facing windows on lower level, dome-lounge on upper level, stereo, TV/VCR/DVD, surround-sound home theater and Wi-Fi. Just exactly what every railfan needs when traveling cross-country.
