I'm coming to the conclusion that it would make more sense for Devon Council or others to do it themselves as a "preserved+" scheme. Build the missing link as cheaply as possible. Once complete upgrades can follow as the potential is revealed.

Dartmoor Railway is already a "preserved+" line which has services at full mainline speeds, ie not limited to 25mph, so it can be done.

Devon Council could retain ownership of the trackbed, provide a grant to help funding and aim for a much smaller government support grant and let a railway society/not for profit organisation get on with it incrementally.

I suspect, providing a means of strengthening rather than rebuilding Meldon Viaduct can be found, it could be done for under £100 million, possibly well under £50 million. It after all cost £12 million to rebuild the Bluebell the seven miles from Horsted Keynes to East Grinstead including land purchase and excavating a 1/4 mile landfill site, a far bigger problem than anything faced on Devons missing link.

It couldn't be done they said, but it was. Basically the local community needs to take the lead.

I think that if you take those very real deficiencies in the assessment of benefits together with the overspecification of the route, pluss the inflated nature of the contingency etc, it all adds up to what looks to be a heavily understated BCR for the L&SWR route.

BCR for HS2 has dropped to 0.6 but Government is still busting a gut to build it.

Indeed. Those that try to portray the BCR as a matter of pure science are living in cloud cukoo land. Building railway links is inherantly political. The question is, how are the regions of England to achieve self determination in transport like the Scotts and the Welsh.

No it isn't. The BCR has been assessed on a range of scenarios of cost and benefits. The most likely score for Phase 1 only is in the order of 1.7. When Phase 2 is included it is 2.3.

It's amazing what you can do with volunteer labour! Using the same business model, would there be sufficient volunteer labour to run, say an hourly service, all week all year, and would punters be prepared to pay a fare of £2 per mile of return journey?

The line from Coleford Junction to Okehampton is already kept running by Volunteer labour and fares are nowhere near £2 per mile of return journey. Trains from Exeter are operated by paid FGW staff.

Plenty of punters prepared to pay £2 per mile of return journey between London and Manchester though. Mile for Mile the bluebell fares are actually cheaper than an open return from London to Manchester.

A fair bit of the specialist work on the Bluebell extension was done by paid contractors, however it seems they were able to get somewhat cheaper rates negotiated than certain other railway companies I could mention, and it seems to me there is a lot the "big" railway can learn from the professionalism and efficiency with which that railway was built.

Offtopic but I'm curious as to why you lumped the Fort William sleeper in with those other two, given that from what I gather it's very popular (correct me if I'm wrong), especially with tourists (walkers, etc.) during the summer

It's busy in the summer, especially around the weekend (Friday night northbound, Sunday night southbound), but the new franchise will keep a six day a week/ fifty two week a year service, which is going to require a large subsidy for most of the time.

Just trying to find an example of something that we wouldn't dare scrap today, but wouldn't necessarily introduce (if it didn't exist), because the "ah, but you wouldn't scrap the Okehampton route if it was currently in operation" argument doesn't work for me (as there are plenty of weak routes/stations that we are keeping in operation with no plans to scrap - but you couldn't get funding to open a station with only a dozen passengers a day)

My position is - if there is funding specifically available for improving railways in Devon+Cornwall, and this money would not be spent on rail at all if it is not spent, reopening the route through Okehampton is probably one of the more sane things you could do with it. That's not to say there aren't other projects in Devon+Cornwall more worthy of money of this order of magnitude - it's just I can't immediately think of any ;). If it's a case, however, of "here's N hundred million pounds, let's spend it somewhere, where doesn't matter", reopening Okehampton would be quite far down the list.

If it's a case of "either use this money to build the Okehampton route or lose it" (which is basically the way that HS2 is being "offered") then fair enough, build it...

...but I previously suggested in this thread other "rail" things that you could spend money on in south west England (doubling the single track sections of main line through Cornwall, re-opening to Portishead, doubling the single track sections from Exeter to Salisbury, electrifying the B&H) - so its not like we are lacking things that we could spend money on.

Your argument seems to be that if Dawlish can't have a rail line then neither can Cornwall or the most populous part of Devon i.e. Plymouth

I just find it odd that those keen for Okehampton to be re-opened are keen to point out how essential it is for a fully resilient railway to Penzance, but there's no need to give Torbay that kind of protection.

Is that opposed to those self appointed experts who feel that we should be forced to stay with a network, designed for half the number of passengers, forty years ago ;)

I don't think anyone is saying that the 1970s railway should be preserved in aspic (?) - there have been many good extensions/ upgrades/ stations built since then - we'd be lost without improvements like the the Thamelink tunnel in London, the Windsor Link in Manchester or the Merseyrail "loop" in Liverpool - we see around four million journeys a year at modern stations like Stansted Airport and Milton Keynes...

...however I don't buy the argument that any new section of railway has to be on the pathbed of something that Dr Beeching closed. Just as the examples I've given above are "new builds", I think that routes like Crossrail and HS2 will be very busy - I don't think we should be hamstrung by ideas like "how can we reintroduce the old LSWR route from Waterloo to Plymouth" and should focus on 21st century problems instead.

Tees Side Airport isn't really a very useful comparison. Salisbury - Exeter and Settle - Carlisle would be a meaningful comparison, and yes, no government would dare to close them. With good reason.

No Government dares close *anything* - not even a basket case like Teesside Airport Station - so the argument that "if Okehampton was up and running then no Government would dare close is" is a strawman one.

True, but it would be the best way of bolstering strategic rail links to the south west whilst at the same time improving local links to Okehampton, Tavistock and the Dartmoor national park.

It depends on the question that you ask. If you want to frame it in terms of "how can we improve local links to Okehampton, Tavistock and the Dartmoor national park" then of course you'll get the answer "reopen the Okehampton route"...

...but if your question is "what should we do in Devon, in light of the recent wettest winter in almost 250 years" then you could get the answer "upgrade the Dawlish wall" or even "don't do anything as the costs would outweigh the benefits".

They are indeed lovely, but they are also real. The ability for people to look for work in a wider area, find education opportunities, attract trade, operate in an area that hasn't ground to a halt through congestion and the ability for the elderly, the young and those who simply don't have the means to run a car, to get around quickly and comfortably are very real indeed.

Those things come at a cost though. If there's not enough demand for a proper hourly bus service from Okehampton to Exeter (and nothing from Okehampton to Plymouth, or Tavistock to Exeter, from what I can find) then that doesn't sound like there are going to be large numbers of people who are going to be relying on an Okehampton railway line (I've already said that Tavistock to Plymouth looks to have a decent demand, based on current bus services - a reasonable bellweather when you remember the seven or eight buses from Alloa to Stirling per hour)

The West Coast main line passes through a very sparsely populated area, yet it links several settlements and serves the area in terms of tourism. By your logic, that would have a poor business case

The "sparsely populated" section of the WCML links Edinburgh/Glasgow (etc) to Manchester/ Birmingham/ London (etc) - and carries thousands of people every day.

An Okehampton route wouldn't carry thousands of people a day. If it were to then I'd be in favour.

You are being disingenuous to suggest that the route would only be of use once or twice a year

The much trumpeted "diversionary" case is based on a handful of times a year though. If the Okehampton route can't stand on its own two feet for the other 95% of the time then it has a week case, sorry.

Worth remembering that there are a number of routes where closure (engineering works etc) sees passengers put onto buses, even if there are potential diversionary routes (e.g. Virgin not always bothering to divert services up the S&C).

That depends on exactly what's being proposed for Option 2. For nearly £400M you can do a lot to protect the railway from the elements.

True

Alternatively the lesson learnt is that the disruption doesn't cost as much of the price of the alternatives?

So therefore doing nothing is the answer, albeit not a palatable one to those affected.

Agreed - it's not going to be a popular answer in Plymouth, but we have to consider the cost of doing nothing, alongside all of the expensive "solutions".

if you want to use business case and 'value for money' arguments can we please see actual passenger numbers for Dawlish, Dawlish Warren and Teignmouth? Bet St Ives on its own would beat all three combined.

Annnd,. by the power invested in me by the cup of tea I currently drink.

Teignmouth , Dawlish and the Warren have three times the numbers (combined) of St Ives

Best not mention Mutant Womprat either, since it smooshed 'em all.

Torbay has a higher combined total than the sea wall trio as well. The only station has that has similar numbers in Cornwall is Truro.

Rapidash has saved me a job!

Also worth pointing out that a large number of those St Ives passengers are making journeys wholly within Cornwall (or no further than Plymouth), so would still have a train service if the Dawlish line were closed, whereas those Torbay passengers are going to be scuppered if there's no train to Exeter.

Something worth remembering when we are told about Cornwall being "cut off" (but people are seemingly less bothered about the "resilience" for Newton Abbott/ Torbay)

That completely understates the value of routes such as Waterloo to Exeter as a diversionary route. This route is neither double track nor high speed, yet on many occasions it has proved vital to keeping the South West connected. It's "day job" role throughout the rest of the year renders it vastly more useful than a fleet of coaches as well, which would also be the case of the Okehampton route were reinstated as single track.

The Waterloo - Exeter line is busy all day long/ all week long (an extra 50,000 journeys a year at Yeovil Junction in the past decade) - it's in need of redoubling - it "washes its face" regardless of the fact it can be used for diversions...

...whereas an Okehampton line would be pretty quiet for 95% of the time. Handy for diversions, yes, but that comes at a large cost (and there are lines needing investment for all year round demands).

But, unless you are building a complete replacement route, you still have the maintenance costs of the coastal route, as well as the costs of upgrading the inland one.

True. And, if you are going to properly maintain the coastal route then the need for diversions elsewhere becomes weaker

For comparison, does anyone know what the cost ratio benefit figures are for the Waverley and HS2 routes?

Do they give cost benefit figures for improving the existing Dawlish line? Could the recent costs of the disruption be cheaper than improving the existing line?

Good point that "doing nothing" is an option - we seem to approach threads like this with the mindset of "how can we spend hundreds of millions of pounds" rather than considering that the "at any cost" approach isn't always the right one

For Waverley, depending who you believe, it is between 0.8 and 1.3. The latter is, apparently, only achieved when you assume significant house building in towns along the route to generate local economic growth and passenger use. Note this is apparently being resisted. The higher figures are also based on a cost south of £300m.

So on the face of it, using the Scottish Government's own numbers, there is a good chance that the Waverley route will make the Scottish nation worse off. Ie that cash would have been much better spent on other projects (including rail projects ) that would make the nation better off. Or being blunt, it is a collossal misallocation of resources.

Nevertheless, those who live along the route, and the people they vote for, will be better off.

Now note the BCRs for the subject of this thread.

I don't think that the Waverley route would be built were it not for the fact that a minority Labour administration at Holyrood needed the support of the LibDems to form/maintain a Government in the Scottish Parliament...

...I'm talking around a decade ago, when the LibDems played hard-ball as the price of them supporting a larger party, rather than the "roll over and have their tummy tickled" approach that they have taken in Westminster...

...with the LibDems having the Borders as one of their "strongholds" back then (it was David Steel's seat at Westminster/ Holyrood, for example), spending a large sum of Holyrood money in "their" area was a price that they were happy for someone to pay for. The business case wasn't important. That's not to say that we should take the same "at all costs" approach in Devon.

I think that if you take those very real deficiencies in the assessment of benefits together with the overspecification of the route, pluss the inflated nature of the contingency etc, it all adds up to what looks to be a heavily understated BCR for the L&SWR route.

If you don't like the answer, then the methodology must be wrong?

Based on the same factors as other schemes, the Okehampton route has a much weaker case than other schemes (all of which could equally make a case for "inflated contingency costs" / "understated demands" etc).

But it is the same for every other rail or transport project at this stage. The cost of the Waverley route at this stage was less than £150m with a barely positive BCR. The cost has now more than doubled as the project has developed and risks understood. You must apply the contingency until such time that you understand the risks.

Like the methodology or not, it is the same for everything. There are literally thousands of rail projects out there with positive cases on the same methodology. So you prioritise those with a good case. Even if the methodology changed radically to be even more favourable to rail benefits, it wouldn't change the batting order of priorities, and this one would be just above the extras.

Note that the current hurdle rate for road schemes is much higher (I have seen 8 quoted), ie the playing field is very much skewed to rail at present, and has been for nearly a decade, reversing what was the case through the 70s and 80s. (And rightly so). But this won't last forever.

Well put

BCRs haven't exactly covered themselves in glory lately.

Alloa must have well and truly smashed its BCR to smitherens given its loadings and I wouldn't be surprised Borders does the same

You remember the good results and forget about the bad results.

Someone (pumbaa, AFAICR) posted a link that showed a graph of recently opened stations and how they've compared to expected passenger numbers. Some are winners, some are losers. Even in the same area we've seen discrepancies (passenger numbers at Newcraighall were significantly below expectation, but they didn't learn their lesson about accurate forecasting and significantly underestimated passenger numbers for the next station to open in Edinburgh - Edinburgh Park).

Worth remembering that there's a difference between whether passenger numbers match/beat the expected numbers and whether a scheme gets the go-ahead - the fact that the Waverley route may beat the benchmark for passenger numbers wouldn't necessarily mean that it gets enough passengers to make a positive business case.

tbtc presents so many disparate opinions, rather on the scattergun principle hoping one of the bullets finds its target, whatever that may be and quoting Uncle Tom Cobleigh and all (now which part of Devon did he come from?) I wouldn't attempt to provide a riposte to the half of them on the grounds of my ignorance. Common to it all, though, is that the Dawlish routeing must be kept because of Torbay and what is good for Torbay must be good enough for everywhere else west of it.
It is unfortunate for Torbay that the weakest link is so near to them but that is a fact, one that's been known about for decades and, in the true British spirit that Nigel Farage is now trying to tap, we must throw our hands up saying 'but nobody told us' and then go back to sticking our heads in what remains of the Dawlish sand.
The populace of Torbay and South Hams (which does not appear to include you) will continue to have their rail link to the outside world but for how long? Why should West Devon and Cornwall be forced to hang on to their coat-tails when an alternative, available and viable route exists for us? I am sure that in an emergency it could be arranged for trains from Newton Abbot to Exeter to be routed via Plymouth and Tavistock, in fact there's a germ of an idea there, a circular serxice from Exeter.

Regarding direct transport links (bus) from Okehampton to Plymouth, Plymouth Citybus operate a popular one via Tavistock.Re no stations or lines closing, tell that to the many who lost the South London Line last autumn after a century of operation, and if you're going to be pedantic about Stockport to Stalybridge I can match you with the Ealing Broadway to Wandsworth Road weekly service which ran its last about a year ago.

Torbay has a higher combined total than the sea wall trio as well. The only station has that has similar numbers in Cornwall is Truro.

Err, my maths seams to be a bit addrift here, below are my workings so that you can check them for me:
Teignmouth - 0.592 million
Dawlish - 0.507 million
Dawlish Warren - 0.146 million
Total - 1.245 million

Given St. Ives is 0.585 million that is a factor of 2.13 times differnce between the two (i.e. about double not the tripple suggested). It should also be noted that only one of the stations just about beats it for passenger numbers.

Also:
Torre - 0.234 million
Torquay - 0.428 million
Paignton - 0.572 million
Total - 1.234 million (which is less than 1.245 million the last time I checked)

Compare that to St Ives and that is a comparable factor of just over 2 (2.11) - i.e not tripple. It should also be noted that not one of these stations beats St Ives for passenger numbers.

Although the Cornish stations tend to be a lot lower, it should also be noted that they are doing so with a lower level of service and with a much longer journey time to most other places.

It should also be noted that no where in this argument is anyone suggeting that there should be two routes in Cornwall, just between Exeter and Plymouth to the benefit of Cornwall.

IIRC Portishead is an already funded scheme and is mostly delayed due to lack of DMU's

The redoubling of the line through Cornwall, although useful could be done in stages including more passing loops. If this were to happen and a more frequent service through from at least Exeter were to occure it would cause even more of an uproar if Dawlish where to be closed again for a long time (even just for engineering works).

The redoubling of the WofE line would require more 158's/159's, which given the lack of DMU's would mean that it is likely to be on the back burner until electrification of the line and/or electrification of a lot of other lines. As even just extending the services which currenly make it to Yeovil would require at least 3 additional units.

Whilst although the fully reopened Okehampton line could also require 3 units (maybe four if end to end journey times including turn arounds go above 90 minutes) to run an houly service, two of those units are currently required for the Plymouth to Gunnislake (hopefuly soon to be Tavistock) with at least 1 unit required for the Okehampton to Exeter section. That could mean that the through service could be done with no additional units required or maybe only one extra.

Electrifying of the B&H would very much depend on what trains are use to run it

I just find it odd that those keen for Okehampton to be re-opened are keen to point out how essential it is for a fully resilient railway to Penzance, but there's no need to give Torbay that kind of protection.

Firstly Torbay services would still be able to rum the long way around, which wouldn't be useful for the local services, but people may still use it if they were going a long way. As even if you had an extra 100 minutes over the time when you could go direct there are people who would be willing to do so rather than get on a coach and then get on the train at Exeter.

Also (even if noone wanted to do that) it would mean that the scrum for coaches at Exeter would be lot less and therefore it would be less of a problem (which for avoidance of doubt would still a pain in the neck, just less so than how it is at present).

There may even be ococians when trains could still get though, but in less numbers than when the line if running fully, when the Plymouth trains could be diverted around and only trains to Torbay would then need to use the line.

For instance the stoppers to Torbay could use one rack whilst engineering works (which there would likely be the need for a LOT of to make the line more resilant) happened on the other track rather than eveyone having to jam onto HST between Exeter and Newton Abbot which then stops at all the stations (i.e. the worst of both worlds).

I don't think anyone is saying that the 1970s railway should be preserved in aspic (?) - there have been many good extensions/ upgrades/ stations built since then - we'd be lost without improvements like the the Thamelink tunnel in London, the Windsor Link in Manchester or the Merseyrail "loop" in Liverpool - we see around four million journeys a year at modern stations like Stansted Airport and Milton Keynes...

I agree, however given the cost of the DAL is basicly £1.5bn to £3bn and saves at most 6 minutes on the journey time (i.e. cost about double that of the reopening of the LSWR) which is unlikely to make any differeance as to whether people use the train or drive and provides no new journey opertunities. As such the next best option is to look at old routes to determine what benefits they can provide. (cf. the proposal for a line to Borden in Hampshire which after looking at many options, including light railand vvarious route, more or less decided on pretty much a reopening of the old line to heavy rail standards)

Yes we shouldn't just reopen lines just because they existed in the past and sometimes a new line would be better.

It depends on the question that you ask. If you want to frame it in terms of "how can we improve local links to Okehampton, Tavistock and the Dartmoor national park" then of course you'll get the answer "reopen the Okehampton route"...

...but if your question is "what should we do in Devon, in light of the recent wettest winter in almost 250 years" then you could get the answer "upgrade the Dawlish wall" or even "don't do anything as the costs would outweigh the benefits".

OK, IF the government decides to upgrade the Dawlish wall and not provide an alternitive link the people west of Dawlish can look forward to many many weekends of no trains as the upgrade works are undertaken. That politically could be as bad as doing nothing (some could argue given the whole point of this is to reduce the risk of west of Dawlish being cut off by train then doing something which make it certain to happen is worse).

Those things come at a cost though. If there's not enough demand for a proper hourly bus service from Okehampton to Exeter (and nothing from Okehampton to Plymouth, or Tavistock to Exeter, from what I can find) then that doesn't sound like there are going to be large numbers of people who are going to be relying on an Okehampton railway line (I've already said that Tavistock to Plymouth looks to have a decent demand, based on current bus services - a reasonable bellweather when you remember the seven or eight buses from Alloa to Stirling per hour)

Although there is no one service which runs an hourly service there is at least one bus in each hour which runs between the two. However, many more people would use a train service as it can beat the queues that they would otherwise be stuck in if they drove.

Also the other point to bear in mind is that the train would likely benefit other places as they would have a more frequent service. For instance there is only one train which arrives at Exeter before 9am (and that arrives at 8:12) from Crediton and only one train between 5pm and 6pm (and that is basicly at 6pm) back again in the afternoon, which is hardly likely to temp people to use the train. A new Okehampton service could improve that and therefore mean that more people use both services as going to Exeter by train becomes a viable option.

The "sparsely populated" section of the WCML links Edinburgh/Glasgow (etc) to Manchester/ Birmingham/ London (etc) - and carries thousands of people every day.

An Okehampton route wouldn't carry thousands of people a day. If it were to then I'd be in favour.

The WCML was a poor example, the Settle and Carlile line would have been a better one to give. It has a reasonable number of people use it, but mostly for tourisum. It has diversionary benefits, which have proved to have been benifitial time and time again (even if they are not always used, but then if it were electrified as the routes that it would provide the diversion for are electrified it may be another matter).

The much trumpeted "diversionary" case is based on a handful of times a year though. If the Okehampton route can't stand on its own two feet for the other 95% of the time then it has a week case, sorry.

Worth remembering that there are a number of routes where closure (engineering works etc) sees passengers put onto buses, even if there are potential diversionary routes (e.g. Virgin not always bothering to divert services up the S&C).

As pointed out before Virgin would need to use DMU's or locos to use the S&C, either of those options could mean that it was more difficulty than it's worth. Esp. given that when people are buying their tickets they tend to know if there are engineering works and there are alternitive route that they can take (i.e. why use the WCML and have to use a bus and add an hour to your trip when you can use the ECML and it be not much different).

Rapidash has saved me a job!

Also worth pointing out that a large number of those St Ives passengers are making journeys wholly within Cornwall (or no further than Plymouth), so would still have a train service if the Dawlish line were closed, whereas those Torbay passengers are going to be scuppered if there's no train to Exeter.

Something worth remembering when we are told about Cornwall being "cut off" (but people are seemingly less bothered about the "resilience" for Newton Abbott/ Torbay)

You may wish to double check peoples maths before thanking them. As pointed out Torbay could still benefit from the diversion route's existiance.

The Waterloo - Exeter line is busy all day long/ all week long (an extra 50,000 journeys a year at Yeovil Junction in the past decade) - it's in need of redoubling - it "washes its face" regardless of the fact it can be used for diversions...

...whereas an Okehampton line would be pretty quiet for 95% of the time. Handy for diversions, yes, but that comes at a large cost (and there are lines needing investment for all year round demands).

No one is suggesting that the redoubling of the WofE line isn't worthy of being done, and as I've pointed out before the reopening of the line through Okehampton could mean that it has an even better case. Yes there is a finate amount of cash, but no I do not think that the redoubling of this line would be never done if the reopening of the line through Okehampton happens.

Good point that "doing nothing" is an option - we seem to approach threads like this with the mindset of "how can we spend hundreds of millions of pounds" rather than considering that the "at any cost" approach isn't always the right one

Do nothing is an option, but then so is closing a lines west of Exeter. Neither are likely to happen though because it would be politically a bad move.

I was not saying that we should spend the money on the LSWR, more that there are problems with whichever option is picked which may not be obvious at first glance (such as the amount of line closures likely required for undertaking the works to the sea wall).

Politicly the choice is:
- do nothing and hope that nothing major happens for a long time
- undertake the sea wall works and hope that the political backlash which may happen when the line is closed during the summer weekends to provide the protection isn't too bad
- reopen or build one of the inland routes and spend more money than the above and have the political fall out from spending the extra money

I was not saying that we should spend the money on the LSWR, more that there are problems with whichever option is picked which may not be obvious at first glance (such as the amount of line closures likely required for undertaking the works to the sea wall).

Politicly the choice is:
- do nothing and hope that nothing major happens for a long time
- undertake the sea wall works and hope that the political backlash which may happen when the line is closed during the summer weekends to provide the protection isn't too bad
- reopen or build one of the inland routes and spend more money than the above and have the political fall out from spending the extra money

No one has said anything about closing the lines for summer weekends for sea wall protection works. That is very, very unlikely.

I know that the ideal is that the works are carried out outside of the peak summer season, however by the time the locals kick off about any works between Easter and the Autumn half term. That doesn't leave many weekends to do very much.

Even if NR were to try and fit all the works into the winter season (when the weather is more likely to stop works leading to over runs), there are likely to be some works which could end up over running (or at least causing line speed restrictions) for prolonged periods of time (i.e. longer than a weekend and the long weekends which are normally used elsewhere being Easter and August would be politically very bad news and Christmas could be problematic due to the weather) or would need to be done when the weather is at least more likely to be favourable for a long length of time.

The only reason that the works done as the closure where able to be done was because the line was totally closed for a long period of time, enabling some fairly significant works to be done. (also the good weather during the works helped, as another storm part way through the works could have added in lost hours and extra work to be undertaken).

The main point of this report is to find ways to ensure that the line isn't closed, yet the cheapest option will guarantee that the line will be closed for periods of time (OK, they will be planned and probably for fairly short chunks of time so less disruptive, but still a closure non the less).

Not necessarily. No one on this forum knows what the reinforcement work is (least of all me), and how disruptive it might be. It could be offshore. It could be non-disruptive. It could just require the seaward track closed, using the leeward track under bidi.

Besides, it's not so much the weather that is a problem, but the tide, and fortunately that is predictable.

On top of that it is proposed to take place over 20 years, so there are roughly 400 weekends that avoid the time between Easter and October plus Christmas.

But that is the case with any infrastrucuture works on any section of track, if the job is big enough odds are it is going to need some sort of lengthy possessions. Week long blocks even on major arteries such as the WCML are considered palatable now and NR are working towards handing back works with 80mph TSRs.

Err, my maths seams to be a bit addrift here, below are my workings so that you can check them for me:
Teignmouth - 0.592 million
Dawlish - 0.507 million
Dawlish Warren - 0.146 million
Total - 1.245 million

Given St. Ives is 0.585 million that is a factor of 2.13 times differnce between the two (i.e. about double not the tripple suggested). It should also be noted that only one of the stations just about beats it for passenger numbers.

Also:
Torre - 0.234 million
Torquay - 0.428 million
Paignton - 0.572 million
Total - 1.234 million (which is less than 1.245 million the last time I checked)

Compare that to St Ives and that is a comparable factor of just over 2 (2.11) - i.e not tripple. It should also be noted that not one of these stations beats St Ives for passenger numbers.

Although the Cornish stations tend to be a lot lower, it should also be noted that they are doing so with a lower level of service and with a much longer journey time to most other places.

It should also be noted that no where in this argument is anyone suggeting that there should be two routes in Cornwall, just between Exeter and Plymouth to the benefit of Cornwall.
--- old post above --- --- new post below ---


IIRC Portishead is an already funded scheme and is mostly delayed due to lack of DMU's

The redoubling of the line through Cornwall, although useful could be done in stages including more passing loops. If this were to happen and a more frequent service through from at least Exeter were to occure it would cause even more of an uproar if Dawlish where to be closed again for a long time (even just for engineering works).

The redoubling of the WofE line would require more 158's/159's, which given the lack of DMU's would mean that it is likely to be on the back burner until electrification of the line and/or electrification of a lot of other lines. As even just extending the services which currenly make it to Yeovil would require at least 3 additional units.

Whilst although the fully reopened Okehampton line could also require 3 units (maybe four if end to end journey times including turn arounds go above 90 minutes) to run an houly service, two of those units are currently required for the Plymouth to Gunnislake (hopefuly soon to be Tavistock) with at least 1 unit required for the Okehampton to Exeter section. That could mean that the through service could be done with no additional units required or maybe only one extra.

Electrifying of the B&H would very much depend on what trains are use to run it



Firstly Torbay services would still be able to rum the long way around, which wouldn't be useful for the local services, but people may still use it if they were going a long way. As even if you had an extra 100 minutes over the time when you could go direct there are people who would be willing to do so rather than get on a coach and then get on the train at Exeter.

Also (even if noone wanted to do that) it would mean that the scrum for coaches at Exeter would be lot less and therefore it would be less of a problem (which for avoidance of doubt would still a pain in the neck, just less so than how it is at present).

There may even be ococians when trains could still get though, but in less numbers than when the line if running fully, when the Plymouth trains could be diverted around and only trains to Torbay would then need to use the line.

For instance the stoppers to Torbay could use one rack whilst engineering works (which there would likely be the need for a LOT of to make the line more resilant) happened on the other track rather than eveyone having to jam onto HST between Exeter and Newton Abbot which then stops at all the stations (i.e. the worst of both worlds).



I agree, however given the cost of the DAL is basicly £1.5bn to £3bn and saves at most 6 minutes on the journey time (i.e. cost about double that of the reopening of the LSWR) which is unlikely to make any differeance as to whether people use the train or drive and provides no new journey opertunities. As such the next best option is to look at old routes to determine what benefits they can provide. (cf. the proposal for a line to Borden in Hampshire which after looking at many options, including light railand vvarious route, more or less decided on pretty much a reopening of the old line to heavy rail standards)

Yes we shouldn't just reopen lines just because they existed in the past and sometimes a new line would be better.



OK, IF the government decides to upgrade the Dawlish wall and not provide an alternitive link the people west of Dawlish can look forward to many many weekends of no trains as the upgrade works are undertaken. That politically could be as bad as doing nothing (some could argue given the whole point of this is to reduce the risk of west of Dawlish being cut off by train then doing something which make it certain to happen is worse).



Although there is no one service which runs an hourly service there is at least one bus in each hour which runs between the two. However, many more people would use a train service as it can beat the queues that they would otherwise be stuck in if they drove.

Also the other point to bear in mind is that the train would likely benefit other places as they would have a more frequent service. For instance there is only one train which arrives at Exeter before 9am (and that arrives at 8:12) from Crediton and only one train between 5pm and 6pm (and that is basicly at 6pm) back again in the afternoon, which is hardly likely to temp people to use the train. A new Okehampton service could improve that and therefore mean that more people use both services as going to Exeter by train becomes a viable option.



The WCML was a poor example, the Settle and Carlile line would have been a better one to give. It has a reasonable number of people use it, but mostly for tourisum. It has diversionary benefits, which have proved to have been benifitial time and time again (even if they are not always used, but then if it were electrified as the routes that it would provide the diversion for are electrified it may be another matter).



As pointed out before Virgin would need to use DMU's or locos to use the S&C, either of those options could mean that it was more difficulty than it's worth. Esp. given that when people are buying their tickets they tend to know if there are engineering works and there are alternitive route that they can take (i.e. why use the WCML and have to use a bus and add an hour to your trip when you can use the ECML and it be not much different).



You may wish to double check peoples maths before thanking them. As pointed out Torbay could still benefit from the diversion route's existiance.



No one is suggesting that the redoubling of the WofE line isn't worthy of being done, and as I've pointed out before the reopening of the line through Okehampton could mean that it has an even better case. Yes there is a finate amount of cash, but no I do not think that the redoubling of this line would be never done if the reopening of the line through Okehampton happens.



Do nothing is an option, but then so is closing a lines west of Exeter. Neither are likely to happen though because it would be politically a bad move.
Stating publicly that your going to do other is politically bad but quietly saying nothing or saying one thing and the not doing it some years later possibly not politically as bad. I prefer politicians to say it as it is but life isn't like that.

Yes, but there are other rail alternatives to get to most places on the WCML. Not so west of Exeter.

Not so south of Bletchley! And barely so south of Rugby (Bedford to Bletchley hardly being up to the job.)

That would be the Bedford Bletchley line that is about to be upgraded, electrified and reopend to Oxford to er provide an alternative route ;)

..but then unlike many stations west of Exeter there are a number of stations on alternative lines within an hour by bus from Bletchley.

Sitting writing this in my study barely a mile from Sheffield : this Sheffield may be on top of a hill but there the resemblance to that inhabited by tbtc probably ceases- its inhabitants could probably be fitted into a Supertram with room to spare. From a Penzance perspective probably shared throughout Cornwall and West, even parts of North, Devon we just want a railway service to Exeter, Bristol, Birmingham, Reading and London that isn't going to get flooded or blown away with increasing regularity. If we want to get to Dawlish or Torbay we must change trains, as there is insufficient demand for those destinations to provide a direct service. Even Plymouth to Totnes and Torbay is now well provided for by express bus services, taking a lot less time than the (indirect) train in the latter case.

It therefore follows that we don't give a damn whether our train goes through Dawlish or not- personally I think the seascape isn't a patch on Mounts Bay, even if the latter didn't have St Michael's Mount as a backdrop, but that's a purely personal preference. So when someone comes along and basically says 'we can spend a lot of time and money getting you through your M.O.T. but don't come back next year because it's basically crocked' we say 'yes okay, but in the meantime could you find us an alternative secondhand, but not in too bad condition that could be brought up to scratch and perhaps we'll add a few mod cons later on' it is galling to be told at the M.O.T. station 'sorry, new regulations on sustainability preclude us from testing anything you bring us other than the original.These are special conditions we impose on the South West because we know you;ll take it lying down and because our Leader has a special affection for you.

Who was it who said 'tell me what conclusion you want and I'll provide the statistics to back it up'?

Know I'll get a lot of hostility for this, so it would be nice to receive some support too.

Claiming major outages are going to be regular enough to worry about after a single occurrence is more than a little alarmist isn't it?

Edit:
Also the service in Cornwall is so dire you would probably get a better BCR for pushing an all new HSL all the way to Truro. Most of Devonwall in commuter country.

This is a misrepresentation of the climate & sea level situation. Admittedly the odds are low of an event occurring in any specific autumn/winter period [eg 2014/15] that is as serious as the one we saw last winter, but there is no doubt that both the frequency and severity of events will rise due to the fact that sea level is rising and the rise is accelerating. The probability is that it will be quite a number of years before anything quite so serious happens again.
The existing route by the sea is an unsuitable location for a major line. A decision needs to be taken soon to proceed with an alternative so that (a) Cornwall & Plymouth are not cut off for a lengthy period due to flooding and (b) less money is wasted on a King Canute exercise.

Most people in favour of a second route would understand that any start of works are likely to be a good few years away (as would be most of the works to strengthen the sea wall). I have even suggested that if the choice was made to have some form of route through Okehampton that it could be built in stages over a number of years. yes that would be politically risky as if the Dawlish line were to be breached again in the period (say 15 years) it takes before there is a full through route that would not go down well, however would then would enable politicians to up the spending and/or the speed of the project to look good, whilst being able to claim that they were right to have supported the reopening.

The only person I'm aware of who has made any suggestions about rail improvements west of Plymouth recently has been against a second line between Exeter and Plymouth.

An Okehampton route wouldn't carry thousands of people a day. If it were to then I'd be in favour.

But a northern alternative route would carry thousands of passengers if the same disastrous consequences happened again along the sea wall or at any of the other neighbouring coastal locations.

From what I can see without considering BCRs and other statistical facts is that the Dartmoor route is the easiest to construct in the shortest possible time. The tunnel alternatives will take much longer to construct and there may not be time if there are further coastal problems.

Even if the Okehampton route were selected and implemented as a single track version with passing loops it would provide the necessary resilience and keep the trains running between Exeter and the South-West 365 days per year as well as providing local services. During any further disruption along the sea wall route passengers would still be able to get to the Torbay area via Plymouth.

I know what you're going to say, the journey time to Torbay will take longer. Yes, it would take longer to reach those destinations, but at least a reasonable rail service could still be maintained with connections to the south-west and stations east of Exeter.

So faster than the permanent ones all the way from Newton Abbot to Plymouth!

King Canute was then, this is now. We can easily hold back the sea from the Dawlish alignment, indeed we must as the area is heavily populated. A permanent diversion of the railway via Okehampton would be the end of significant rail service to Paignton and Totnes - they would end up like Tavistock is now - a forgotten backwater.
We are committed to 4m sea level rise, flood defence is essential - otherwise we risk the ECML being cut at Peterborough.
Doing nothing for the moment discounts the cost of flood defence works into the future.

By 20 years time I'd be inclined to place more confidence in the RNLI than the orange army! Also think that tidal coastal systems are still poorly understood and there are recent instances of where the opposite effect to that intended has been achieved by 'coastal management' in both North and South Devon. The basics might be just like trying to shelter a harbour but the crazy bit is you are also trying to run a frequent main line railway on top of the harbour wall!

I agree - a basic line would be a start and then it could gradually prove itself! (Or not - but I'd take the risk!)

The odds of getting a decent summer two years in a row is also pretty low, but is now happening in Cornwall for the first time since 1975/6 and serious flooding in Newlyn has occurred 5 times since 1990, 4 of which were within last nineteen months, so don't assume statistically that Dawlish won't suffer badly again for a few years at least. After all, one guy won the National Lottery jackpot twice within its first few years and I once saw somebody win an E-type Jaguar on Covent Garden piazza by throwing a six on each of five dice simultaneously. The organisers were gutted, but I guess the insurance premium on such an unlikely event was fairly low.

In the not too distant future a 'Dawlish diversion' will have to be constructed. South Devon should keep a main line railway.

I am a little surprised that NR priced a double track main line via Okehampton on the same trackbed, with a few replacement structures.
(A rebuilt railway with much higher speeds maybe following the A30 in places would be the 5* option!)
My choice would be
A single track railway with generous passing loops, and double track Crediton to Exeter (Barnstaple service) would work out a lot cheaper, and straightening the curves and less work reinforcing embankments etc.
If the passing loops were bidirectional, an express train could overtake a stopper.
The cycleway could also co exist, bringing much business & tourism to the line.
Plymouth is an important City which has huge potential, and would certainly benefit from better transport links. (The airport closed, partly that the site was not ideal) So better rail links are the best option. Extending the M5 to Plymouth would be an expensive and controversial option!

Probably most lines in the country have important improvements/ schemes waiting for cash.
Transport infrastructure is something HM Government is well failing to spend enough money on.
