I am no fan of privatisation. In fact I would prefer the railways to be renationalised. BR▸ wasn't great but it did provide MUCH better value than the current set up.
BUT the current set up is the worse of all worlds. The problem is that the likes of First have no "skin in the game". They own very little because they are no more than thinly capitalised spivs. That means that when the revenue predictions or performance go wrong (as they will eventually) they can walk away (see NX and SeaCo) or demand fresh subsidies (see Southern). I'd be happy with NR» staying more or less as it is now but with the TOCs▸ moving to be much more like the FOCs▸ or else just being contractors rather than franchisees.
It is instructive, I think, to note that whilst the FOCs have doubled their productivity since privatisation due to investment in equipment (which BR would never have ordered), the productivity of TOCs (ie the real cost of moving a passenger a mile) is virtually unchanged since the days of BR despite record levels of investment, advances in technology and a year on year increase in customers of the kind that most businesses would kill for.
The Franchise system is how the government made it.
The TOCs are "thinly capitalised" because that is how the government wanted it with the trains owned by leasing companies. Notwithstanding this First Group did buy some additional
HSTs▸ a few years ago - I assume creating their own separate leasing company to do it.
Chiltern did put some capital into track improvements earlier in their franchise, but then they had a 20 year franchise. Government, however decided they did not want any more 20 year franchises so TOCs cannot put money in unless they have a very short term return on their investment.
As for TOCs walking away their ability to do this is down to the terms of the franchise contract.
DfT» tried to improve these with some system of guarantees but these were so complicated that they led to the collapse of the whole west coast and
GW▸ franchise renewals a few years back. I am not sure what they are doing on this for new franchises now being let.
The alternatives as I see it are:
a) More long term franchises like Chiltern with incentives for franchisees to invest;
b) Everything being open access and leave it to the market what services are run (that would be the FOC model); or
b) Management contracts like London Overground where all the investment comes from government (if I understand correctly).
