The US is a tough place to build out High Speed Rail because: - the dense cities with good intra-metro transit are either all already in the Northeast Corridor or somewhere else entirely and too far apart from each other: Chicago is much too far from NYC, DC, San Francisco, Seattle - elsewhere, you find big metropolitan areas that are the right distance apart (~100-200 miles) but are impossibly spread out and have bad transit, such that only a small subset of your potential customers can get to where the station would be, or to where they're trying to go within the metro once they arrive; e.g. Texas Triangle (Dallas, Austin, San Antonio, Houston), Florida V (Tampa, Orlando, Miami), I-85 (Atlanta, Charlotte, Raleigh)
