Although NSE▸ had inspirational leadership by C Green Esq even he could not deliver the investment needed. Although the trains are expensive we have probably the lowest average age train fleet in europe provided by private capital. The infrastructure has been a mess but that goes back to Railtrack and PUG2 and instead of leaving the company to sort itself out HMG decided to step in when then sensed a political opportunity. This caused years of chaos - if Railtrack had been left alone the system would have been sorted much more quickly.
The problem with the investment however is that despite the network being imporved and the age of rolling stock decreasing, it does not mean things have improved. The most popular and suitable intercity stock seems to be the hst as it can go almost anywhere with a large amount of capacity and a buffet, essential for intercity services. Post privatisation has seen the introduction of voyagers for example which seem to be the equivelant of the old alphaline services in regards to service provision and comfort as opposed to intercity levels despite being intercity services. Then you have the infrastructure investment which seems very short term focussed as can be seen with the Ebbw Vale line re-opening were everything was done to a price, but now required even more investment to increase frequency which would have been cheaper if a little bit more investment took place in the first place.
I'm not saying that
BR▸ would be better as there were clearly problems, but the privatised mess we currently have is just as bad, if not worse. Maybe instead of regional franchises, it would have been better to have a
UK▸ railway franchise that allows investment and cross subsidy of the whole network with a clear partnership between a franchise holder and network rail with long term planning and investment with suitable investment in rolling stock and infrastructure whilst reducing the needless duplication of staff amongst other things that have greatly increased costs.
At the end of the day, it seems neither the government nor private companies are any good at running the railways, what it requires is to be similair to the Royal Mail set up, free to run itself without input from civil servants or politicans but still owned by the government.
