The biggest mistake made was by Labour with their nationalization. Once you lose market force solutions, you either legally steal money off people to subsidize something and in Labour's case give in to their paymaster unions, which is why train drivers earn much more than drivers in private bus companies.
Once a company is in public ownership then there is no rational efficient allocation of capital. Is is all done for political reasons. BT was another classic example of this, where you had to wait years for a phone line, once they were privatized and had competition, then they had to raise money to invest, compete and survive.
What they should have done, if the branch lines were so viable, is privatise them and let imaginative entrepreneurs, cut costs and market them effectively, which is what the tourist / preservation societies have done.
Personally, I don't think the railways should be a subsidised form of transport. Make it work or turn them into motorways seems a sensible way forward to me.
As usual Rods2, you have hit the nail on the head. From a financial point of view a fresh approach should have been exercised in running the railways, after two big mistakes had been made.
1/ The railways should never have been nationalised in 1948 as The Big Four could/ would have successfully run their systems IF the Labour government had paid the railways the true market value of using their services during WW2.
2/ The 1955 Modernisation Plan had been constructed in a way that really got to grips with the true value of the railway and laid down sensible, imaginative, and viable plans for the future. It in fact was a failure of policy making by the then Conservative government, which required much later tinkering and ham fisted adjustments. We ended up with a shambles of a plan, that resulted in the acts made by Dr. Beeching.
