    Trains aren’t the solution to every problem. They are slower than planes, don’t work on water, and need infrastructure (tracks). They are great where they do work, but where electric planes work, there’s no need to put them down.

      They seem to be since electric planes don’t really exist for passanger flight and are unlikely to exist in a future near enough to be meaningful. For water we got boats so that’s the one place where trains aren’t the solution.

      Tracks are a lot cheaper than airports as far as infrastructure is concerned while also going to more places and the speed of travel is a worthwhile sacrifice to stop pollution from planes. Plus sleeper trains are so comfy compared to the hell that is the cramped airplane seat with less leg room than you need to actually fit your legs there.
