yes! rail is amazing in term of efficiency, a common high speed train has around a credit card worth of contact area with the rail for the whole train! it's also quite relaxing and socially interesting.

the problem is that rail is "boring" and rarely get sufficient funding.

It also allows for much more productivity while travelling, which is important for business travellers.

Energy efficiency will become radically less important as energy cost continues on down.

Then other things become more important, and drive choices.

Rail is quite a lot less flexible than air travel. If you have a plane you can pretty much go anywhere that has a strip of asfalt of the right length. With rail you need to lay out the track between the two points with all the difficulties involved in that.

It's wired vs wireless ethernet. Which do you have in your home?
