Amtrak took over intercity passenger rail operations from the private railroads on May 1, 1971. Initial service on the Seattle–Portland portion of the corridor consisted of three daily round trips–one long-distance train running all the way to San Diego, along with two corridor trains inherited from Burlington Northern. There was no corridor service south to Eugene, and no service to the Canadian border at all. The trains were unnamed until November 1971, when the two corridor trains were named the "Mount Rainier" and "Puget Sound" and the long-distance train became the "Coast Starlight".
