It wasn't really engineered, just plonked on top of the landscape! Doesn't help that you've got the Cotswold escarpment on one side which is all sliding downhill anyway, with the embankment getting in the way of surface water flows. As it is that...

Could be for safe access, looks like the start of a scaffold stairway with uppermost landing in place with ladder access.

These railways were built before people fully understood soil mechanics, I guess the soil here is prone to being affected by rain and over time will decide to move around. I believe at the time of previous slips the line recognised the issue ,...

Geotechnical engineering knowledge was approximately zero in that day and age, basically. E.g. I seem to recall, in the original Chicken Curve repair, that when they dug down, the found a buried grass layer; the earth of the original embankment...

Relax. There are many spaces in Robertsbridge carpark which are just never taken, particularly on the run-up to the yard gates. I live there locally, and have never been unable to park at Robertsbridge. There are ALWAYS empty spaces, and will be...

How odd. That seems to be a scaffolding tower up next to the top of the bridge - but the propping diagrams show all the temporary structure for that as being underneath the bridge. I wonder what this scaffolding tower is for? Noel

I'm not sure the EA would have anything to do with it - the watercourse there is not an EA "main river" as far as I can see so the LLFA would be the local council. Unless there's some other reason I've probably missed? Sent from my PGT-N19...

All details of the propping would have to be approved by the Environment Agency because of interference and disturbance of the watercourse. The design would have to be checked/approved/accepted to ensure that it will not collapse under the loads...

Any chance we could get some images? The drawings in We're Proactively Propping Bridge 42 show 4 (two pairs) temporary (presumably) piers, erected in the river bottom, which will have to go in before the propping can be installed. Noel

To be fair to NYMR, I'm not sure I'd necessarily expect calcs to be released to the public. Even with confidence as low as we all have with the railway atm, I think it's still reasonable to expect someone competent has designed the propping...

I believe that the components used to form the propping are on hire from a supplier, and will need to remain in place until early 2027. If the crane is due to arrive on Monday 20th April, that constitutes a slippage of two weeks on the original...

Actually, not. As @Steve points out, since the propping is temporary, and will not involve any changes to the permanent structure, there is nothing about it in the application (and thus in the plans therein). Still, there's enough detail shown...

https://www.nymr.co.uk/news/were-proactively-propping-bridge-42-to-ensure-2026-season-opening This is the sketch of the propping. Presumably, this is included in the plans.

The propping and repairs are two separate things. The repairs require planning permission as it is a listed structure and will be invasive. The propping is not and is not referred to in the planning application. The scaffolding referred to in...
