"The rail network should be re-nationalised and run as a not-for-profit organisation staffed by people with no financial incentive whatsoever in saving money - merely doing their jobs properly, for an appropriate salary and no bonus,"
Been there, done that, Andy (and the T-Shirt wasn't much to write home about). Arguably the UK railways’ finest period was between the “grouping” of 1923 (when dozens of small railway companies were grouped into the “Big Four”) and WW2. That period of excellence would probably have continued but for the war. In 1945 the railways were in a terrible state having taken a severe pasting during the hostilities and during which maintenance was reduced to the bare minimum and improvements were necessarily curtailed to almost nil. The government saw the only way out of that mess as nationalisation.
The nationalised system seemed to work OK up to around the early 1960s. By then the 1955 Modernisation Plan was in full swing and steam power was being rapidly replaced by diesel and electric. Then it all seemed to fall apart. In my view the main reason for that was that there was indeed an abundance of staff “with no financial incentive whatsoever in saving money.” Alas many of them also had no incentive whatsoever to do their jobs properly by putting their customers first. Anybody who remembers the railways from the 1970s will know what I mean.
The Big Four were autonomous companies that ran their own railways lock, stock and barrel. They provided and maintained the permanent way, signalling, rolling stock and motive power. I will agree that, whilst vast improvements have been made, rail privatisation has been less than satisfactory. The principle reason for that was the ridiculous model used which separated train operators, infrastructure providers and rolling stock/motive power provision. It’s a dog’s breakfast with almost limitless opportunities to shift blame for failure between those providers (lubricated, naturally, by vast sums lost in administration and legal fees).
The current model provides virtually no competition (which was said to be the principle aim of privatisation) on the vast majority of routes and it is doubtful if that can ever be achieved. The answer is to re-engineer the service into autonomous groupings similar to the Big Four (without short term franchises). The thought of returning the service to its state in the 1970s where staff cared not whether passengers lived or died is just too horrendous to contemplate.
