RMweb Premium Northmoor Posted June 10, 2022 RMweb Premium Share Posted June 10, 2022 1 hour ago, corneliuslundie said: The other thing public bodies do is to commission consultancy to avoid doing things; then of course by the time the consultant reports things have changed so further consultancy work is needed - by friends at court quite often. And announcing consultancy about a project is often used as a smokescreen for the fact that nothing is actually intended to happen, but it gives the appearance of progress. Cynical? Surely not. Jonathan I think this is perfectly true and you should consider that politicians will frequently commission such consultant's reports about the things you and I think shouldn't go ahead, as for those that we think should. Rather than the MP be forever remembered for telling some single issue obsessive retiree that a dual carriageway by-passing his particular village would be a monumental waste of public money and for goodness sake shut up about it, the MP will commission a report costing 99% less than building that by-pass, to deliver the evidence. It is then the member of the public who demands another report, then another and another until they eventually get one that produces the conclusion they wanted. There are plenty of fairy tale railway reopening campaigns that are based on the most spurious figures in "professional" reports; I'm sure I saw one about the Fleetwood branch which implied that about half the town's population would be commuting to Preston every day. 3 Link to post Share on other sites More sharing options...

It probably depends on whether the area is scheduled for residential development in future, so may have more to do with minimising noise rather than any aesthetic considerations.

John Possibly, but if noise was a consideration then why are so many new housing estates built right next to busy A roads and especially motorways. 6 1 Link to post Share on other sites More sharing options...

So basically a tunnel under the disused runways next to a car strorage facility. Odd place for a tunnel unless like has been said the whole place is to be turned into housing and they want the space over the lines. 4 Link to post Share on other sites More sharing options...
RJS1977 Posted June 12, 2022 Share Posted June 12, 2022 I wonder if the "green tunnel" is perhaps not so much to hide the railway, as a way of maintaining a wildlife corridor so that wildlife will be able to cross the railway when complete. 1 2 Link to post Share on other sites More sharing options...

That's what it basically looks like. The tunnel goes right through what was the centre of the old airfield. The village of Chipping Warden lies to the SE of the airfield, on the other side of the A361. Unless there is to be more of this "green tunnel", on the other side of the A361, then HS2 will whizz right past, uncovered, just to the north of the village. Looking at Google Maps, the A361 now bypasses the village and there are roundabouts to nowhere, situated by the old airfield site. It appears that the re-routed road is planned to continue at some point in the future, so it's quite possible there are plans for housing developments in that area. https://www.google.co.uk/maps/place/Construction/@52.131957,-1.2674126,5943m/data=!3m1!1e3!4m5!3m4!1s0x48772505a72bbf17:0xde52f6ffeed70daf!8m2!3d52.1446544!4d-1.2684116 . 5 Link to post Share on other sites More sharing options...
kryten65 Posted June 12, 2022 Share Posted June 12, 2022 The tunnel will extend south of the A361, the large muck heap to the right of the end of the excavation next to the road is where the temporary overbridge will be to allow access to that side. That was a new reason for my driver to get delayed while waiting to be offloaded "I can't move because the press are here" 5 Link to post Share on other sites More sharing options...

woodenhead Posted June 12, 2022 Share Posted June 12, 2022 Bit more detail here https://assets.hs2.org.uk/wp-content/uploads/2022/05/AWN_Notice-of-Green-Tunnel-Works_May_2022.pdf The map shows it like east to west to make it easier to read, but it's actually SE to NW cutting above Chipping Warden and below Aston Le Walls, straight through the middle of the old runways - literally X marks the spot on the map. 5 Link to post Share on other sites More sharing options...
kryten65 Posted June 20, 2022 Share Posted June 20, 2022 Progress continues at Chipping Warden, albeit slightly slower than planned but it's a long way from somewhere like done, this is a good example of how the construction goes, first the team put a number of central piers in place, then the same number of arch wall units, then roof sections Then the crane moves back across to do the arch walls and roof units and repeat ad infinitum.. There are units with additional purposes, there will be central piers with ducts to allow airflow to move between the bores and emergency escape doors to allow evacuation for a stopped trains passengers to be taken away from any potential situation. The excavation progresses along 150m to the right of the picture, where they need to break out a thick strata of rock, before getting down to the required level, I'll try and get a pic of this work if anyone is interested 12 3 Link to post Share on other sites More sharing options...

RMweb Premium jamie92208 Posted June 22, 2022 RMweb Premium Share Posted June 22, 2022 It's a while since I posted my tunnel progress chart so here is the latest version. All three machines were updated about a week ago. Some significant progress. Florence and Cecilia are now averaging 18 and 17m per day respectively which is above what I think was their design speed of 15m per day. Dorothy however is going a little bit slower at 8.5m per day but last week got past the 75% distance for he first drive. Hopefully the next machine will set off from West Ruislip soon.

Currently they are standing there, just through self weight, later on they will pour a concrete slab in the bottom to tie the arch walls to the central pier, and that will be where the track will sit. Then a membrane goes over the tunnel and backfilled to cover, but that's a few years off yet! 3 1 4 Link to post Share on other sites More sharing options...
