Anyone who remembers when the railways were nationally owned/operated knows that it was an absolute disaster. British Rail was a standing joke for incompetence.
The privatisation was done badly, and for that the Major government was at fault. The track owners and train operators should not have been separated. The problem we now have is that all the franchisees are also bus operators who want to do in the railways once and for all.
That is what should be looked at and dealt with.
