The streamlined back end of California Zephyr CB&Q 377, named the 'Silver Solarium', must have looked like something out of a Buck Rogers movie when it was introduced in 1948. The car could accommodate 50 passengers and operated with the CB&Q until 1970, when it served Amtrak until retirement in 1985. It was then sold to a private party who restored it for private charter service. The oscillating red Mars light and the streamlined tail lights added to the unique look and acted like a beacon to passengers walking in and out of Denver's Union Station.
