Funding
Funding for the route is provided separately by the states of Oregon and Washington, with Union Station in Portland serving as the dividing point between the two. As of July 1, 2006, Washington state has funded four daily round trips between Seattle and Portland. Washington also funds two daily round trips between Seattle and Vancouver, BC. Oregon funds two daily round trips between Eugene and Portland. The five trainsets are organized into semi-regular operating cycles, but no particular train always has one route.
