There is a piece in Railway Gazette about that ElevArch demonstration, and NR have a video (or say they do, I can't get it to run).
If not playing via Network Rail itís also available on YouTube:  https://youtu.be/KhumV315nFk

I would have thought jacking the bridge up was an excellent solution.

1) Convince the local nimby's its a great idea
2) Jack it up one side only first, and crack the arch.
3) Demolish troublesome bridge on safety grounds
4) Stick the cheapest and most ugly bridge in its place.

Problem solved.  Cheesy

From personal inspection of this particular structure over a number of years, it is clear that the structure is showing significant signs of distress. I would not be surprised if some form of vehicle weight restriction were to be applied in the future, particularly if we have a harsh winter and freeze/thaw effects disturb the brickwork. Next time someone drives over it, take a look at the road surfacing and the undulations.

I think that it's a 3-arch bridge, unlike the one shown jacked. It is evidently in poor condition, evidenced by the bracing applied. I'm surprised that it could qualify for listing.

I suggest that NR has a chat to the local building inspector about serving a dangerous structure notice for demolition. That trumps listing.

Then a weekend with bus replacements and some gelignite sticks....

And if feeling cautious, do not closely follow any heavy vehicle !

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

800s and 802s can now run in passenger service from Causeway to Swindon in the down direction only.

That's under electrical power, right?    They can still come back with passengers under diesel power?

Should book a concrete delivery and get that chap involved who took out the bridge parapets  on SWTís network a few years ago.  But do it while trains arenít running as a concrete mixer landing on an EMU isnít all that safe...

Network Rail have tweeted something from BBC Radio Wiltshire about electric services starting from Swindon this morning.

https://twitter.com/networkrailwest/status/1057902936389509120

Also this from Swindon Council

Let's hope that services are more 'up the pan' than 'down the pan' from this morning then ! Shocked

IETs have been running on electric in the down direction to Swindon since Monday (apart from switching to diesel between South Moreton and Steventon). I saw a 800/3 9-car running on electric near Baulking Grange between Challow and Uffington yesterday.

I've read elsewhere that electric running in the up direction from Swindon is due to commence next week. Given the electrical interference issues previously experienced, NR and Hitachi are taking a cautious approach!

Good picture in this evening's Bristol Post, showing the state of electrification at Hatchet Road (just after Bristol Parkway):



Image from Bristol Post

Incidentally, I can't help noticing that this is another bridge where the height warning is given in US Customary units only - is there a pattern emerging here? https://goo.gl/maps/uEs1mQrrHaC2
