So, to sum up, why has this growth been down to things other than privatisation? Because East Coast, a nationalised company, have achieved the same growth. Because fuel prices and road congestion have risen and people have said they choose to take the train because of this, meaning more passengers. Because population has risen and this would undoubtedly mean more passengers. And because a further passenger growth has come from increased investment, mostly from a nationalised company.
East Coast would not be experiencing the level of growth without the groundwork of the private sector, which itself was undermined by the public sector incompetence. Public sector entities do not work in the interests of the public due to the undermining of the destruction between the authority and the executive. The result is that they are incapable of meeting customer expectations.
This is all evidence that the growth that the railway has experienced is down to things other than privatisation, and that privatisation has simply been able to take credit from these external factors. The only evidence I have been given for privatisation being the cause of passenger numbers increasing because they have increased under privatisation and didn't under BR.
It is not possible to prove that numbers would have increased if BR had continued to exist, but evidence of BRs poor service record indicate that it would not automatically be the case. Further, it has been new ideas, such as the DLR that have been the foundation of that growth. The Liverpool Street redevelopment would not have been possible without private sector involvement and that was the baseline for a number of future projects. Had BR never existed, it is unlikely that passenger numbers would have fallen so low, instead there would have been a focused effort to restore the industry and provide it with professional management.
In short, the involvement of public sector bureaucrats and jobs-worths in any sector of the economy is self-serving, destructive in the long-term and against the demands of the market.
Under that umbrella, I could also say that fully privatised railways would still use steam powered trains, as BR fully replaced them and the LNER, LMS, GWR and SR didn't. This claim would obviously be madness. Now I've presented my evidence, please enlighten me as to how privatisation specifically has brought about this railway growth?
Steam engine construction only continued after the war because of governemnt interference, like-wise it was public sector diktats that continued to procure slam-door stock and and undermine customer service.
All of your evidence for that comes from free market theory that I have heard many times before; more financially efficient and better services due to the profit incentive, lack of state intervention means they can try what they want, while competition between private companies means that they drive the prices as low as possible. It makes sense, but is however all theory.
Free economies are the most successful in the world - there is no proof needed, just a bit of education concerning the merits of hard work for those that think otherwise. For examples of statism look to the former soviets, the Eurozone, any of a number of latin america nations, and former communist nations in asia. All have undermined customer service through economic manipulation and state control. Again, no furtehr proof needed.
It does not cover the fact that the railways are not profitable ...
Rail is operating at break-even if not profitable in the L&SE and long-distance sectors. It is provincial services that are only meeting around 50% of their operation costs that is preventing them from becoming profitable overall. So your premise is flawed.
However, elimination of staff costs will address problems with provincial services so long as there is no further statist intervention. The result will be that the consumer gets a high quality service at lower cost than at present, with reduced input from government.
BR was not perfect, but it was also around when the railway was seen in a different eye and unions were so powerful, and it also achieved so much in light of that (the HST? The replacement of steam?). A future nationalised railway would probably be different; East Coast is a bit of proof for that.
I was around t the time, and the service was abysmal; trains halted partway through journeys with staff walking off work, wild-cat strikes, passengers having to travel in cabs to make sure the driver competed the services, etc, etc. Under private control, managers can manager, and Bolsheviks are less able to sabotage customer service, though there are still a good few of them about.
East Coast has not proved anything as far as I can see.
