>>1560269Federally funded, state-managed, county-planned 400-mile stretches.
California messed up big by not giving the worst job (eminent domain) to the counties. Most counties are in the 30 mile center-to-center range, which is roughly what good intercity rail needs to keep +100mph averages on dedicated track. You tell each county in between two major cities "Hey, plan your own route with these minimum curves and slopes and get a station, or we'll just use state highway land and leave you behind."
400 miles is Atlanta to Louisville, Los Angeles to Phoenix, Phoneix to el Paso, Chicago to Minneapolis and many more. It's also the correct length for a crew to perform a full loop in one work day.
Hand management of each line over to one state and let the politicians use them as dick measuring competitions.
