One of the big advantages of air travel is that it is much more competitive than train systems. This is due to the high costs of train tracks resulting in a natural monopoly. Without even the threat of competition there is little incentive to control costs. This often gets magnified by union and government involvement. So despite the theoretical efficiency advantage of trains they are often more expensive than other forms of transport which is a real shame.
