Train of Tomorrow Goes into Service

General Motors toured its all-dome concept train, the Train of Tomorrow, across the country beginning in 1947. After the tour ended, Union Pacific purchased the four cars and assigned the Astra-Dome train, powered by an Electro-Motive 2,000-horsepower diesel locomotive, to pool service on the Seattle-Portland run. Passengers found a new way to enjoy the scenery when they rode in the Sky View diner, Star Dust chair car, Dream Cloud sleeper and Moon Glow lounge-observation car. The cars operated until the early 1960s.

Union Pacific's Moon Glow car survives today. Rescued from a Pocatello, Idaho, scrap yard by the Promontory Chapter of the National Railroad Historical Society, it has since been donated to the Utah State Railroad Museum at the Ogden Union Station.

In 2012, Union Pacific celebrates the shared stories that have shaped our country since 1862. To mark our 150th anniversary, we invite you to explore how the nation’s largest railroad came to be and how UP continues to build America with innovation and tenacity, touching the lives of nearly every citizen.
