Prior service Passenger train service between Seattle and Portland—the core of what became the
Cascades corridor—was operated as a joint partnership by the
Northern Pacific,
Great Northern, and
Union Pacific from 1925 to 1970, with the three railroads cross-honoring tickets on their Seattle-Portland routes. When Great Northern and Northern Pacific were folded into the
Burlington Northern in 1970, the reconfigured partnership continued to operate the Seattle-Portland service until the creation of Amtrak in 1971. Service between
Vancouver, British Columbia, and
Seattle was provided via the Great Northern / Burlington Northern
International, and between
Portland and
Eugene by
Southern Pacific.
Amtrak era in 1981, listing the
Mount Rainier, the
Pacific International, and other since-discontinued trains 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. Passenger rail service to Vancouver,
British Columbia, was restarted on July 17, 1972, with the inauguration of the Seattle–Vancouver
Pacific International, which operated with a
dome car (unusual for short runs). The train was Amtrak's first international service. The corridor expanded south of Portland to Eugene on August 3, 1980, with the addition of the
Willamette Valley, which operated with two daily round trips, financially subsidized by the State of Oregon. This left three trains on the Seattle–Portland corridor: the regional
Mount Rainier and the long-distance
Pioneer and
Coast Starlight. This level of service would remain unchanged for 13 years.
Expansion in the 1990s , with NPCU at the head of the train. In 1994, Amtrak began a six-month trial run of modern
Talgo equipment over the Seattle–Portland corridor. Amtrak named this service
Northwest Talgo, and announced that it would institute a second, conventional train on the corridor (supplementing the
Mount Rainier) once the trial concluded. Regular service began on April 1, 1994. Looking toward the future, Amtrak did an exhibition trip from Vancouver through to Eugene. Amtrak replaced the
Northwest Talgo with the
Mount Adams on October 30. At the same time, the state of Oregon and Amtrak agreed to extend the
Mount Rainier to Eugene through June 1995, with Oregon paying two-thirds of the $1.5 million subsidy. Service to Canada returned on May 26, 1995, when the
Mount Baker International began running between Vancouver and Seattle. The state of Washington leased Talgo equipment similar to the demonstrator from 1994. The
Mount Rainier was renamed the
Cascadia in October 1995; the new name reflected the joint Oregon–Washington operations of the train. A temporary commuter rail service using Amtrak trains was deployed in September 1997 between
Union Station in Portland and
Vancouver station during a full closure of the
Interstate Bridge for repairs. The
free trains had ten round trips and drew an average of 1,335 passengers per day; the low ridership was attributed to the isolated location of Vancouver's station. A third Seattle–Portland corridor train began in the spring of 1998 with leased Talgo equipment, replacing the discontinued long-distance
Pioneer. The other Seattle–Portland/Eugene trains began using Talgo trainsets as well, while the Seattle-Vancouver train used conventional equipment. In preparation for the Vancouver route receiving Talgo equipment as well, Amtrak introduced the temporary
Pacific Northwest brand for all four trains, dropping individual names, effective with the spring 1998 timetable.
Amtrak Cascades in Vancouver, British Columbia Amtrak announced the new Amtrak
Cascades brand in the fall 1998 timetable; the new equipment began operation in December. The full
Cascades brand was rolled out on January 12, 1999, following a six-week delay due to an issue with the seat designs on the Talgo trainsets. Amtrak extended a second train to Eugene in late 2000. From the mid-1990s to the May 12, 2008, Amtrak system timetable, full service dining was available on trains going north out of Seattle's
King Street Station to Vancouver. The southern trains to Portland briefly had full dining services until the May 16, 1999, system timetable. In 2004, the
Rail Plus program began, allowing cross-ticketing between
Sound Transit's
Sounder commuter rail and Amtrak between Seattle and Everett on some
Cascades trains. The corridor continued to grow, with another Portland–Seattle train arriving in 2006, and the long-awaited through service between Vancouver, British Columbia, and Portland, eliminating the need to transfer in Seattle, beginning on August 19, 2009 as a pilot project to determine whether a train permanently operating on the route would be feasible. With the Canadian federal government requesting Amtrak to pay for border control costs for the second daily train, the train was scheduled to be discontinued on October 31, 2010. However, Washington State and Canadian officials held discussions in an attempt to continue the service, which resulted in the Canadian government permanently waiving the fee. Two additional round trips between Seattle and Portland were added on December 18, 2017; an early morning departure from each city and a late evening return, enabling same-day business travel between the two cities. On the first day of service of the new timetable, a
train derailed outside of DuPont, Washington, south of
Tacoma. Service resumed using the old timetable without the additional round trips.
Pandemic cuts and restoration In March 2020,
Amtrak Cascades service north of Seattle was suspended indefinitely after all non-essential travel across the
Canada–United States border was restricted in response to the
COVID-19 pandemic. Amtrak crews ran practice trips between Seattle and Vancouver, British Columbia, in February 2022, and service between those two cities resumed on September 26, 2022. The round trip between Portland and Vancouver resumed on March 7, 2023, restoring the second Seattle–Vancouver trip that existed prior to the COVID-19 pandemic. Seattle–Portland service expanded to six round trips on December 11, 2023, adding the two additional round trips between Seattle and Portland originally intended to start in 2017. In 2025, the completion of a new customs inspection area at Vancouver's Pacific Central Station will allow
Cascades trains to eliminate a secondary inspection stop in
Blaine that is performed by
U.S. Customs and Border Protection officers. The modified customs procedure is expected to save 10 minutes on southbound trips. A new maintenance facility at the Seattle Yard is scheduled to open in late 2026. ==Route==
