I don't understand why people wanting the railways publically owned again want it.
"Oh because it worked fine when it was British Rail" isn't going to work; to go back to that would mean one whole load of changes in the industry. Even then, in my opinion it will just fall apart as you lose the competition. Prices will no doubt rise (given it would be at least part-owned by George Osborne and his chums, that's a given anyway) and people will once again complain.
