Lots of comments about how this is a good thing, but if private companies are still running the trains, and fares are set centrally, how are they expected to make a profit? Reduce the staff, or reduce the staff salaries. Either way, unions get involved and there will be strikes just like the "good old days". More retail in and around stations perhaps? I look forward to being able to just a buy a single ticket from X to Y and one that perhaps doesn't cost 5-10 times as much as it would to drive.
