Follow up to previous postings on high speed rail in America, this news about “a new study released today by America 2050 identifies the high-speed rail corridors with the greatest potential to attract ridership in each of the nation’s megaregions. Corridors connecting populous regions with large job centers, rail transit networks, and existing air markets scored best. The study also recommends that the federal government adopt a quantitative approach to evaluating future investment in high-speed rail. The 56-page study, entitled, High-Speed Rail in America, cites ridership potential as the number one factor in determining if a corridor is suitable for investment, identifies the specific conditions that generate ridership demand, and scores each corridor according to strength in those areas. The top performing corridors in each region determined to have the greatest potential demand for high-speed rail ridership include corridors such as: New York-Washington, DC; Chicago-Milwaukee; Los Angeles-San Diego; Tampa (via Orlando) to Miami; Dallas-Houston; Atlanta-Birmingham; Portland-Seattle; and Denver-Pueblo.”
