I see a lot of good explanations for the status quo, but I'm surprised nobody mentioned the more fundamental problem that you simply can't overtake a train. Airplanes can fly relatively independently of each other, compared to trains who have to share tracks and more limited train stations. This means you just can't compete on the level that budget airlines can. Spirit, RyanAir, etc: they helped bring down prices across the industry. Flying used to be $300, but after relentless competition, even the more expensive airlines are now far cheaper than they used to be. The inching down of leg room, saving pennies on drinks and food, paying for extra luggage; that kind of brutal cost saving just doesn't happen without merciless competition. And it's comparatively impossible to start a RyanRail: you can't just dump your trains in between the other ones. It's an inherently hard field to compete in. Even in the UK and NL, where different private companies compete, they do so by winning bids for sections of tracks, and exclusive access to those tracks. That's not the same as airlines. If only one airline could fly LDN->BCN, it wouldn't be $25. (case in point: KLM & SLM had a monopoly on flights Netherlands <-> Suriname for a while. The day they lost it, prices dropped >50%). Most of the other things (salary expenses, track upkeep, etc) would follow if they could compete harder. We could have said the same about flying two decades ago; nobody would have predicted a $25 LDN->BCN, yet here we are. (this is just my theory, and it's hard to conclusively disprove, therefore quite a weak one..)
