> there is no chance outside of some absurd contrived scenario Well, in the USA, any train that is interstate is required to be built as if it was a freight train, even if it's only carrying passengers 1 mile. And jet engines get 1% more efficient per year. So it is possible that a jet airplane will be more fuel-efficient for interstate travel than a train at some point.
