The only good thing about the current service is that bad suppliers can be got rid of and not have their contract renewed. Complacency and militant unionism is what bought this country to it's knees back in the 70's. British Rail new they had a monopoly - hence didnt give a stuff about anything. The Govt cant / couldn't sack British Rail - as they owned them.
I'd me very careful in thinking that Nationalisation is the panacea of all things good - as it isn't.
