The Cascade was an passenger train of the Southern Pacific on its route between Oakland, California, and Portland, Oregon, with a sleeping car to Seattle, Washington. The Southern Pacific started the train on April 17, 1927, soon after the opening of its Cascade Line between Black Butte, California, and Springfield, Oregon.
At first the train offered first class service and a $3.00 extra fare; it became an all-Pullman train in 1937. On August 13, 1950, the Cascade became a streamlined coach/Pullman train with a triple-unit diner and cars painted in two shades of gray. The next 21 years saw a decline. The Seattle sleeper was discontinued in 1966, the triple-unit diner came off a year later. By 1970 the train was down to five or six cars and ran only three days per week. Amtrak would take over the Cascade on May 1, 1971, and would combine it with the San Francisco - Los Angeles Coast Daylight routing the train through Oakland and eventually renaming it the Coast Starlight.
The Shasta Route into Oregon was completed on December 17, 1887, connecting California points to Portland, Seattle, and the Pacific Northwest. The Oregon and California Express was the first passenger service; it later gained fame as the Shasta Limited. But the route over the Siskiyou Mountains of Southern Oregon was difficult with steep grades, sharp curves, and subject to landslides and washouts. During the reign of Edward H. Harriman Southern Pacific began building a better route via Klamath Falls. Government involvement in the affairs of Harriman and the SP would delay completion for 18 years.
