The Cascade was a 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.

The Lark was an overnight passenger train of the Southern Pacific Company on the 470 mile run between San Francisco and Los Angeles.
