From The BBC» Battered Dawlish rail line to get higher wall
A coastal railway line that washed into the sea five years ago may soon be protected from the wind and waves by a new wall.
The sea defences in Dawlish, Devon, collapsed during storms on 4 February 2014, leaving the tracks dangling above the waves.
Network Rail has applied for permission to raise the wall from its current height of 5m to 7.5m.
The plans will need to be approved by Teignbridge council and the government.
Network Rail said the wall would give "far more protection from waves and extreme weather" and claimed it is "future-proofed" against rising sea levels. I suspect this will need merging Network Rail say it will future-proof (the infrastructure) against rising sea levels and provide far more protection from waves and extreme weather. Does this mean that the line will be just as open and trains just as able to run through Dawish as they can run through (say) Yatton no matter what the tide, wind, weather, train types in use are, 364 days a year? |

Before submerging... I think, as SandTengineer says, it's simply buying time rather than an actual solution. |

There's a feature on Dawlish in Rail 871, which concludes: All of this leaves the 'Northern Route' [via Okehampton] as the only logical alternative that can serve a distinct market in its own right while still providing crucial diversionary capacity when needed.

More fiddling whilst Rome burns........   This doesn't address the fundemental underlying issue of the need for a diversionary route away from the area. ..and indeed they say it doesn't. What they do say about wider issues is this: These plans have been submitted to Teignbridge District Council with the knowledge of the Secretary of State for Transport and the outcome of the council’s decision will help inform government’s decision on next steps for the South West Rail Resilience Programme. That looks to me like their pitch is "if we can't strengthen this railway line (which does protect your town too, you know), we'll have to build another one as the main line and that would probably mean closing this one". |

Where does that 2.5 m come form? Or rather where is it going - not on the top, judging by the pictures. So presumably it's to be made higher at the bottom. This picture suggests just that:  Somehow I can't see that - loss of width of a very narrow beach, and what it does to the view inland - being at all popular. |

With Torbay, Teignbridge and the South Hams seemingly not worthy of having any 'crucial diversionary capacity'. That far more densely populated part of Devon will, during disruption, continue to be relegated to Rail Replacement Buses while trains trundle across the edge of Dartmoor to satisfy the dewy eyed lovers of the LSWR▸ .

Dawlish Avoiding Line, Now. I totally agree BNM. I think we discussed on here before about the GWR▸ 1930s plan to build the diversion but still have stations for Teignmouth and Dawlish on it, so they wouldn't be cut out  |

Good to see the arguments continue! What the Dawlish Avoiding line entails is a much higher cost (and no sea views as inland), continued responsibility to maintain the seawall and no gain in fare take - only an ongoing maintenance cost. Do you propose closing the existing line?
The Okehampton route brings the railway much nearer to a large area (OK not highly populated). Can be built (in railway terms) quickly as a mainly single track high speed route along an existing formation which would be useful when engineering works/emergencies occur anywhere between Plymouth and Exeter - not just around Dawlish.
Regrettably I rather doubt if either plan will be built (unless there is another major issue along the seawall) as there is no money!

No. The sea will eventually do that job. |

It is not just the sea wall that has to be considered. There are the cliffs to the east of Dawlish which are not the most stable. Another engineering solution is needed here.
Whilst I would like to see the Southern route return, I believe focus should be on getting the Okehampton and Tavistock lines open first.
Once those are completed then it may be worth looking at linking them.
If an inland route is to be built at Dawlish can you justify keeping the original route?

This is not a zero-sum game.
At some point a DAL may well become a necessity, but in the medium term the Okehampton route is much cheaper and would be a net gain - more options for more people, and more resilience.
No-one is seriously suggesting cutting off rail links for a million people in order to put 8,000 back on the map, and anyone who thinks there would be much left for LSWR▸ fans to get dewy-eyed about if that line was re-engineered and rebuilt hasn't seen the Borders Railway!
