<i>Train of Tomorrow</i> Goes into Service
General Motors toured its all-dome concept train, the <i>Train of Tomorrow</i>, 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.
