France has one of the best and fastest train systems in the world. There's really no reason for people to fly, but they still do.
Reliable certainly not.
On time even worse.
Could you explain this? I'm struggling to understand how something becoming very cheap can be considered an (economic) failure? Isn't that something the market optimizes for?
EDIT: Perhaps you mean expensive rail is a market failure?
The relative time on the airport is not high.You can literally come to the airport just a few minutes before your departure (and many people in fact do this). Also most airports are in my opinion much better organized than train stations.
