Climate change and the GWR Mainline.

[Ptrstv]

I gather that once again high seas closed the Great Western Railway main line to the South West at Dawlish over the weekend.

Any updates from anyone?

As global warming heats up the oceans the water they contain will expand, let along any extra water coming from melting ice caps and this must put the line at more frequent risk of flooding.
How easy would it be to open up the old LSWR route via Okehampton and Tavistock to Plymouth?

Whell the rising sea level is supposed to be one result of global warming, but dont forget that Britain is also rising because it is still recovering from the weight of ice from the last ice age. I think Britain is also tilting with the west coast rising faster then the east coast.

This give me an idea for a new post....

To move the line inland will potentially cost Billions - certainly a lot more than it costs NR to maintain the sea wall. It's also a very scenic stretch of line - would be a shame to lose it.

I recon a possible soloution would be to raise the sea wall, or if things get that bad, put the railway completely under cover. It's a bit drastic but much cheaper than moving it inland. Trains would also be able to run through storms.

You wouldn't think sea water woukld affect plastic so badly

It's called 'isostatic uplift'. The north and west is rising, while the south and east sinks.......and I live in Hull (gulp!). Anyone got a cheap inflatable that will house me, my wife, the kids and the cats and the dog while still giving room for an 'N' gauge layout? Or a design for a floating baseboard?

5 years on and the trains are still getting a splash of salt water on a seasonal basis.
How much info has changed or been re-invented since they first cast global warming on the world's populous. Excessive rainful and flooding seems to have caused the Seven Valley Railway huge problems lately and that is likely to mean similar problems for other Heritage Railways where rivers and flooding are prevalent.

It's all tosh, as will hopefully be revealed as the East Anglian University inquiry gets under way.

I think money is the root of all evil!!

The line there has always been battered by the sea ever since it was built by Brunel no matter what you do you will never stop it.
I myself have been through there many times with sea coming over and believe me it isnt a very nice experience, they do have single line working over the up line when it gets really bad.
As for going inland there has been talk about it many times, there is an old line from Heathfield Newton Abbot to City Basin Exeter closed in 1968 link below
