Half the problem with a disintegrated railway, hopefully the new plan of TOC▸ 's running track and trains might help, but full privatisation is the best answer.
I can see arguments that vertical integration could help, but full privatisation? That seems to me more a matter of political or economic dogma.
There is the argument that the government is doing so badly let the private sector take over, but then given the mind set of our government some will argue that they are doing so badly in order to give them an excuse privitise the whole thing.
But then they couldn't keep their hands off it when it was privitised.
