I promised myself I would maintain a dignified silence on this. But can’t help it, sorry. After this I will withdraw from the debate.
As some of you know I worked closely with the team who produced the 2008 report, and still do.
The latest development has nothing to do with a change in attitude by the Secretary of State, the press release happened to go out in his name. Neither has there been a change in attitude at Network Rail, which was already looking at how to increase capacity on the Brighton Main Line, and is looking at all options, this being one of them.
A few points about the 2008 report. There is not ‘general agreement that the 2008 study was deeply flawed’ within the rail industry, i.e. Network Rail, Southern (plus, incidentally, new franchise bidders) and the DfT, who like it or not are the rail industry in that part of the world. There is, naturally enough, agreement by those who are campaigning for reopening, but that is a little different.
The report DID include wider economic benefits and DID assess the impact of improved connectivity across the region. It also did examine through trains to Brighton, which was quickly discounted as the time penalty for reversal beyond Lewes made changing more realistic. (The remit for the report was very much to reopen the line as quickly and cheaply as possible on the old alignment, and not to build across virgin countryside as required for a west facing connection at Lewes). Nevertheless, from memory new flows to Brighton made a decent proportion of the traffic generated. However some of the issues above (and much more) didn't make it to the final cut of the report – which was all explained to the Board, which commissioned the work, at the regular review sessions.
All the assumptions, inputs and methods used were discussed with the Board and agreed by them. Indeed the Board agreed to distort the business case in favour of reopening by a) allowing some pretty optimistic assumptions about the state of the former track bed and thus reinstatement costs, b) removing the required optimism bias from the BCR calcs, and c) including optimistic sensitivity tests to demonstrate what level of passenger use would drive reopening. None of these would be acceptable in a funding submission to DfT (or indeed Scottish / Welsh Governments). The Board included members from relevant local authorities, and the MPs for both Uckfield and Lewes, the latter of whom was exemplary in his conduct, challenging every assumption, input, method and result. And accepting them, even where he did not like it. The Board did not include anyone from DfT, and they had absolutely no influence on or input to the report. Indeed when they rather cheekily asked for an advance copy of the report to see what it said, they were refused point blank. The first they knew what it said was on publication.
So back to the crux of it. There are only ever 2 reasons to re/open a new railway :
1) For wealth creation, sometimes called economic regeneration
2) To relieve a congested part of the network, to enable (1)
Every other* successful line reopening in the past 2 decades has linked an area in need of (or planned) economic regeneration to a city/region that offers employment potential. Ebbw Vale, Maesteg, Alloa, Airdrie-Bathgate, Larkhall, Mansfield, Snow Hill II, Aylesbury Vale with East West rail to come etc. etc. (*I'm sure someone on the forum will correct me.) It is fair to say that this does not apply to Lewes - Uckfield, neither of which could be termed economically deprived areas, and betwixt them lie only fields. As an aside, the reason the traffic is bad in that part of the world is that most people can afford cars and tend to use them, something that cannot be said of the majority of folk in Ebbw Vale. Being a regular visitor to both places, I can vouch for that.
So, perhaps the best hope for Lewes – Uckfield is as part of a wider network capacity upgrade for London to the Sussex coast, but then there are alternatives. Croydon has to be sorted first to unlock much of this - there is the potential for another Reading sized project there – and work is underway now to resolve Gatwick. But what about south of Gatwick?
My personal view is that if we are to upgrade 20 miles of existing line and build 8-10 miles of new railway in Sussex, potentially with some new tunnel to get through the South Downs, why not do it alongside the existing Brighton Main Line? There it can serve known demand, known growth areas, and improve the journey times / experience for all those who use it today. Done properly it need not be disruptive while built, and will benefit considerably more people than the alternatives.
And finally, the route to Docklands from a wide variety of Brighton Main Line (and branches) stations from 2018 will be change at Farringdon for Crossrail. No need for another new railway there for a while yet.
