A 2019 Business Case Analysis, conducted by the Washington State Department of Transportation (WSDOT), detailed the benefits of implementing an ultra-high-speed ground transportation system connecting the Cascadia region. The investment and implementation of the transportation system would transform the region into a globally competitive, sustainable megaregion, according to the study.

“The ability to travel each segment between Seattle, Portland, and Vancouver, B.C. in less than an hour will revolutionize the way we live, work, and play in the Pacific Northwest. Moreover, it helps us preserve the natural beauty and health of our region by enabling faster, cleaner, and greener trips between our region’s largest cities,” stated Gov. Jay Inslee in the Business Case Analysis.

Key findings of the study, which builds on previous Ultra-High-Speed Ground Transportation (UHSGT) studies conducted by WSDOT, include:

  • Ultimate potential to carry 32,000 people an hour using capacity to schedule many more trains.
  • Estimate between 12 percent and 20 percent of total current intercity trips would shift to UHSGT.
  • Estimate conservatively between 1.7 million and 3.1 million riders annually upon opening.
  • Estimate annual revenue of between $160 million and $250 million upon opening.
  • Can be built within the 2017 estimate of $24 billion to $42 billion in up-front construction costs.
  • Estimate $355 billion in economic growth and 200,000 new jobs related to construction and ongoing operation of the service.
  • Reduction of six million metric tons of CO2 emissions over the first 40 years and potential for zero emissions by using clean energy sources (hydro, wind, solar).
