It is quite annoying when people mention the South West and HS2 in the same breath. It seems some naughtiness by the HS2 Action Alliance is to blame because HS2 has nothing to do with funding for the legacy network, just in the same way that CrossRail doesn't (as both will be funded the same way from what I understand).
I don't see a CrossRail Action Alliance group kicking up a stink about the amount of money that is spent on CrossRail every year, and as Alan Marshall points out on the latest blog post on
www.railnews.co.uk:
Whilst the need for investment is obvious on the South West corridor, HS2 has nothing to do with existing rail budgets so is irrelevant to anyone apart from the mischief makers. Electrification and IEP are examples of current investment
Yes, it annoys me to.
We've had many years of the "left" arguing that (insert big public spending project here) "is a fraction of what we spend on Trident" (as if this guarantees that its value for money)...
...and the "right" arguing that (insert big public spending project/ tax cut here) "is a fraction of what we spend on Overseas Aid".
Recently we've had people arguing that (insert big public spending project here) "is a fraction of what we spend on Bankers Bonuses".
It looks like we're now going to be for a period of people arguing that (insert local railway project here) "is a fraction of what we spend on HS2".
What should matter is the cost/ benefit ratio. The fact that we are spending more on bigger projects doesn't suddenly justify the business case of anything else.
We're probably going to have to get used to this daft argument though, now the press has picked up on it. You can argue "what benefit does HS2 give Devon" but then you could argue "what benefit does (investment in one region) give (investment in any other region)". Electrifying the GWML doesn't really benefit me in Sheffield, but I think its got a good enough business case to go ahead.
You are choosing to overlook one important thing in your reasoning, indeed many lines have no realistic diversionary routes, however there isn't another mainline which is at such great risk of periodic closure. To take an example which has cropped up earlier, there is no realistic diversion for York to Northallerton, but there is only some tiny fraction of the risk of this line being closed as compared to the risk at Dawlish.
I've mentioned other coastal lines on this thread (like the North Wales Coast line which was recently closed, the clifftop bits of the ECML near places like Berwick and Stonehaven), but these don't have people clamouring for diversionary lines to be built for "resilience".
Perhaps its pertinent to point out here that bus services between Okehampton and Tavistock were cut from hourly to two hourly in 2008 and Devon County Council have been nibbling away at the subsidy ever since.
In comparison, the bus frequency from Stirling to Alloa was seven or eight commercial services an hour along the main road (plus three an hour via Stirling University and the back road via Menstrie etc), which is why it isn't surprising that the train line has attracted a decent number of passengers.
AFAICR Tavistock to Plymouth is a twenty minute bus service, so that suggests there's a (smaller) market for a train service. But the Tavistock to Okehampton service... doesn't look like natural rail territory.
Seriously though, the BCR methodology is lousy though. Lets not forget, it manages to pluck some mythical figure from the air for road tax "lost" from the treasury not to mentioncounting abstraction from another route as a negative, even if that other route is crowded and justifies investment to enhance capacity in its own right, yet it can't monetise the positive effects of alleviating the massive disruption when the line is blocked, either planned or unplanned.
It's a joke really.
You mean it doesn't give the answer that you want?
I can assure you, Salisbury to Exmouth Junction is pretty bloomin long, and don't forget, it has only just had a loop put in at Axeminster allowing an hourly service, so its hardly been over supplied with capacity through the decades
Surely making this a double track line is a big priority in terms of "resilience" then?
This is just people looking for an excuse to reopen the Southern route
Agreed
How busy is the Gunnislake branch? No capacity/demand for one train per hour to each terminus?
Gunnislake itself gets around seventy passengers a day, Bere Alston gets a similar number, the rest of the rural stations are pretty quiet (until you get to Devonport)
My view is it addresses the problem in a similar way to ECML diversions via Lincoln. Yes it may be slow, yes it may extend journey times, but time and time again through trains are was passengers say they want.
Lincoln has around a hundred thousand people, which is five times the combined population of Okehampton and Tavistock. If these intermediate places in Devon were anywhere near the size of Lincoln, I'd have no problem supporting a line.
