They are of course reusing the Connaught Tunnel out in the east. A google/ flit through some of the material gives a sense of how much work they feel they need to do to bring a tunnel which only closed in 2006 (although admittedly one built by the Victorians) up to a suitable standard for modern use.Not that surprising, really - there are plenty of other schemes where they've bored a new tunnel or alignment as its cheaper/ simpler to do (e.g. Crossrail doesn't use any existing tunnels under London AIUI - its all new AFAIK)
We're speculating about a lot of unknowns, as probably is whoever wrote the DfT report, but I don't find it as unbelievable as you that a new tunnel compares favourably to refurbishing an old one. It'll depend heavily on what work needs to be done, of course.A clear thought process but not a logical one. It would suggest that a trans pennine scheme involving the expense of blasting a new tunnel through the pennine hills would be more likely to get past the cost-benefit analysis than repairing and kitting out an existing tunnel
Regardless, what is believable is that a new tunnel on a better alignment could offer much bigger benefits (safety, reduced maintenance, perhaps built to a European compatible gauge etc) than opening the old one.
It starts to come back to the argument I fear we've had before about whether it's more likely for something that is cheap to be built than for something that is expensive but offers juicier benefits. Linking nicely to debates on Uckfield-Lewes. The difference here is that there are reasonably sized communities at either end of Uck-Lew that are currently poorly linked for their proximity, whereas Woodhead doesn't really have that.
And one of the big reasons neither proposal has got all that far is that both routes go through relative wilderness rather than somewhere useful and intermediate. Hence in both cases people turn up and suggest an alternative and more direct new route as an alternative to the slightly obfuscated 'problems' offered as a motivation for re-opening.
