My company prefers we take trains now for anything under 6 hours drive time away (we used to fly). In addition I was reading an article that made mention that more people have found trains to be much less hassle than ariports (Nothing like sitting in an airport for 3 hours pre-flight.) for shorter distancesbetween major cities, so it could be demand driven. i.e. If you have enough people to fill the train at 100% fare, why not raise prices to 120% fare and make more and fill at only 80% capacity leaving room for last minute travelers at 125% fare.
