> You obviously understands my point that railways require massively more infrastructure than air travel […] Debatable. First there is all the land, then all the runways that need to be maintained, the terminals, the jet fuel (refinery, pipelines, storage tanks, local pipes and pumps), the entire local/regional/international air traffic control system (controllers, towers, radio, radar, beacons, ILS/GPS). Train tracks take up much less space, train stations are much smaller, coordination on fixed tracks less complicated that managing planes criss crossing the sky, and trains can run on electricity (so you leverage the existing power grid).
