I wonder is the extremely dry February followed by a very wet March accelerated the rate of collapse? If so, that's ominous for the whole network, as climate change will bring such conditions more often.
The GWR ad was in the copy I bought my mother this morningAll three editions today have got a house ad on P15 for their puzzles app from what I can see here -- can't see a GWR ad anywhere? Yesterday's edition had a GWR one on P15 for London <> Cardiff offer.

I am sorry to keep going back to my hobby horse, but if the route (and others) were to be electrified, most civils and repairs and upgrades happen at the same time. I just cant help but feel that if Didcot-Oxford had been electrified when they said a few years back, attention would have been paid to this viaduct at the same time. It would also help mitigate to a degree, climate change. Lighter electric locos would also put less load/stress on the bridge.I wonder is the extremely dry February followed by a very wet March accelerated the rate of collapse?

Although I agree with you, there is a question as to how badly the structure was degrading at the time electrification would have happened. It is entirely possible the problem would have been thought small enough at electrification and therefore minimal work done to stabilise the ground.I am sorry to keep going back to my hobby horse, but if the route (and others) were to be electrified, most civils and repairs and upgrades happen at the same time.

The only traction that would be any different would be the use of 387s for Turbos. IETs would still be bimode for the Cotswold line and freight/XC would still be diesel for the run to So'ton.Lighter electric locos would also put less load/stress on the bridge.
No they don't, the electrifcation scheme would pretty much be funded to do exactly what its end state would be, not upgrade structures etc unless they were a requirement to deliver the scheme.I am sorry to keep going back to my hobby horse, but if the route (and others) were to be electrified, most civils and repairs and upgrades happen at the same time.

Not to mention it’s highly doubtful any splitting would’ve occurred at Didcot, so the 387s would’ve been 8 cars, and therefore far heavier than a 166.The only traction that would be any different would be the use of 387s for Turbos.

For a bridge that's less important, because only 1 car is going to be on a span at any timeNot to mention it’s highly doubtful any splitting would’ve occurred at Didcot, so the 387s would’ve been 8 cars, and therefore far heavier than a 166.
Wow. That surprises me.No they don't, the electrification scheme would pretty much be funded to do exactly what its end state would be, not upgrade structures etc unless they were a requirement to deliver the scheme.
Hello,The only traction that would be any different would be the use of 387s for Turbos. IETs would still be bimode for the Cotswold line and freight/XC would still be diesel for the run to So'ton.
What electrification would have done is ground surveys for the masts etc and a structural investigation of the bridge to determine the need for any remedial work. The ground investigations in particular may have revealed this problem earlier.
However a 4 car 387 is still heavier than a 3 car 166, so the weight difference isn’t that much, and there is still the repetitive loading, of which there is more, and that is the issue in this case.For a bridge that's less important, because only 1 car is going to be on a span at any time
Nice one, thanks for sharing!Further to my post at #369, photo of page 15 in my edition of today‘s DT with the GWR London to Oxford advert:
Thats delaying the train behind it.This may be a miles-travelled per crow-flies miles record: Didcot to Morris Cowley - via Bicester. 8.5 miles as straight line, but must be 100 now..

They are very lucky that Chiltern had the curve built to Oxford!
5 mph T boards should surely have bern on the other side of the bridge?! Especially the one on the down line!
Why? Standard railway project. Why is an electrification project going to sort out anything else unless its funded to? Various projects may share the access if it aligns, but I wouldnt expect say a signalling job to be doing a track renewal.Wow. That surprises me.
Whacking the schedules in and taking the delay minutes by the looks of it, 1G27 is going to be late.The Oxford Banbury Road stone traffic also diverted via the Chilterns after the Easter break;

I guess I wear rose-tinted glasses to be truthful. I probably should learn to live in the real world. I can’t help but go off- topic here (sorry mods) but if say Southport to Manchester got electrified I really would hope that bridge issue in the Wigan stations area would get sorted at the same time. I bow to your better knowledge and I don’t even live in the UK ( but my brother does as an architect/designer for London Underground), I just need to remove my rose tinted glasses I guess!Why?

The difference is that bridge at Wallgate would have to be sorted out to permit installation of OLE.I guess I wear rose-tinted glasses to be truthful.

Yes, we live north of Radley and they percussive-piled the mast foundations past us, heading north. Not sure how far north but possibly to Osney Bridge and maybe as far as the south side of Botley Road bridgeHello,
I don't post much, as there are people on here with far more knowledge than myself. What I would like to add is that much of the overhead electric piling had already been done between Didcot and Radley. If you look carefully as you creep along on restrictive signals you will see the cast metal tubes sunk into the ground. Many now covered in bramble.
The project was scrapped in haste halfway through, I'm no structural engineer but I suspect surveys may have taken place as piling has already taken place in many areas of this line. I can't remember the nearest piles to the viaduct I expect someone can add more detail to this.
At this point probably needs to run no matter what or it will have knock on effects to the supply chain. Best of a bad bunch to get it in then try and find a better path later.Whacking the schedules in and taking the delay minutes by the looks of it, 1G27 is going to be late.
I tend to agree With you.At this point probably needs to run no matter what or it will have knock on effects to the supply chain. Best of a bad bunch to get it in then try and find a better path later.
Nothing more than a semi-educated guess... but the timeline for the Botley Rd works is now to fully replace the bridge during a second extended closure in 2024. So perhaps it's simply a case of get something done now to get the route reopened and then use the time when the line is going to be closed anyway to do a permanent replacement.I saw some stuff on Twitter that was saying that 10 weeks was for a bodge, and a fully new bridge will take a year and will be done once the bodge is in place.
I guess if there's movement they will need to do some deep piling?

It *may* depend where you bought your copy from. All national newspapers are printed at more than one site, which allows for regional adverts - e.g. an edition printed in London might have the GWR advert but an edition printed in Manchester won't given the circulation will be to the Midlands / North where GWR isn't so relevant.
