Rationale
Improved rail linkages along the Pacific Northwest cities would provide an improved alternative to car and air travel along the route. Ancillary benefits include a reduction in road congestion, reduced travel emissions, and improved business productivity as travel becomes cheaper, faster, and more convenient. Building a separated high speed rail corridor would also increase freight capacity, although this idea is not currently being acted on. Proponents of the Cascadia high-speed rail also believe that it would help the three international airports in Vancouver, Seattle and Portland operate more efficiently and collaboratively, improve international trade and promote tourism.
