David Booth @caleydave.bsky.social · 04/10/2026If they did they would need to be careful about throwing stones in glass houses. They considered all material of the old restoration project theirs and have no respect for the original copyright holders. To the point there are pictures in books/exhibits they had no right to give permission to print 000
David Booth @caleydave.bsky.social · 03/10/2026Yes it is odd, still a picture account is the small fry compared to some of the people I have upset over Barnton Quarry. 110
David Booth @caleydave.bsky.social · 03/10/2026Kelvedon Hatch, Anstruther and Hackgreen were all set up at that sweet spot in the 90's where the old equipment was being sent for scrap and they could have their pick. In my time the vision of Barnton Quarry was accuracy, but now it's Being filled with what is cheap or available. Fantastic book! 010
David Booth @caleydave.bsky.social · 03/10/2026"I was there, Gandalf" "I was there 3000 years ago" Photo credits for the one circling the internet should to to "Grant More", with the original credit being with the Air Ministry. As an observation, Barnton Bunker appears to prefer to skip attributing credit or observing copyright. 110
David Booth @caleydave.bsky.social · 03/10/2026The sad part, as I realise you can't see what I can, is I am now blocked. 330
David Booth @caleydave.bsky.social · 03/10/2026Well that is sad 😢 Picture This Scotland is not to blame the account is only reposting a picture from a source which should be authoritative but has got it wrong, it is not Picture This Scotland's Mistake. If the reaction to a correction is to block then why bother in the first place ? 120
David Booth @caleydave.bsky.social · 03/10/2026Before I along with the Barnton Quarry Restoration Project were unceremoniously kicked out; as both BQ and KH were still the original size and had the operations room floored over, we were deliberately trying to restore the operations room so they would be different experiences. 120
David Booth @caleydave.bsky.social · 03/10/2026I love an R4 Most of these sites were either cleared or, following government roles, had little in them other than beds, tables and chairs. So KH is filled with lots of stuff (some miss labeled) collected at a time the stores were being disposed off. 110
David Booth @caleydave.bsky.social · 03/10/2026If you squint closely at the map on the wall of the Sector Controllers Cabin (left side) you will make out the outline of the south east coast and the Thames estuary. There were 4 R4 buildings built: Caledonian - Barnton Quarry Northern - Shipton Eastern - Bawburgh Metropolitan - Kelvedon Hatch 230
David Booth @caleydave.bsky.social · 03/10/2026Skipping over the shortening of name to "Barnton" Bunker (geographicaly and historicaly wrong) This Picture isn't off Barnton Quarry, it is actually of Kelvedon Hatch, another Sector Operation Centre built to the same R4 Building design. It was a set of official and secret photographs produced. 160

David Booth @caleydave.bsky.social · 28/09/2026I was consultancy but the bulk of the business was managed security operations centre. (We triaged and acted on security alerts). There was employee speculation that not every client knew. If so, some clients would have woken up on Tuesday to their IT security being unmonitored. (This was 2025) 011
David Booth @caleydave.bsky.social · 28/09/2026With outsourcing tech/IT so common if there was a risk it could well have been low. I can believe they had no warning having gone through an Administration. I worked for 8+ years at a computer Security company which filed a Notice of Intent on the Thursday and ceased operating at 5PM on the Monday. 140

David Booth @caleydave.bsky.social · 26/09/2026Fantastic local knowledge, thanks for sharing, I will see if I can cross reference it with anything. There were special arrangements for warning dockyards and shipping (with varying levels of planning/implementation) There was another mains Siren at "Henry Robb Ltd., Victoria shipyard, Leith Docks" 100
David Booth @caleydave.bsky.social · 26/09/2026For an example of an industrial user in Edinburgh with evidence of a Siren remaining we have the old Alexandra Dock pumphouse in Leith. 011
David Booth @caleydave.bsky.social · 26/09/2026It was not uncommon for certain big industrial customers to have Sirens connected to air raid warning system which, in some cases, would be used by said company. During the Transition to War a Law was to be passed restricting the use of hooters, Sirens and the like to avoid confusion with warnings. 121
David Booth @caleydave.bsky.social · 26/09/2026#SirenSaturday I had resisted posting buildings where I found no obvious remains of a Siren. Breaking that rule today with a factory hooter. "T. & H. Smith Ltd, Blandfield Chemical Works, Wheatfield Road, Edinburgh" This was given Carrier planning number 254/47 in the early 1960's. 131

David Booth @caleydave.bsky.social · 19/09/2026No Vibe coding, just bad coding but we are slowly getting there and I have enjoyed the tiny amounts of time I have been able to spend on this project. It needs to actually resize to screens, especially mobile, before I let people get their hands on it directly. #SirenSaturday #EdinburghPoliceBox 020
David Booth @caleydave.bsky.social · 15/09/2026I agree, perhaps a hope for the long term future. It's an A-listed lump of buried concrete, with a surface brick blockhouse, in a nature reserve. There is no fortune to be made from the site, only spent on maintenance. And those who visit deserve to be safe and get an accurate history. 010
David Booth @caleydave.bsky.social · 15/09/2026I can recall the restoration project manager telling concerned locals the site wasn't to be used for raves, which for as long as we had influence was true. Everything the successor "Barnton Bunker" project has gifted us is at best blighted by short term thinking. 010
David Booth @caleydave.bsky.social · 15/09/2026As part of the defunct Restoration Project I ran hardhat tours in what was a shell of a derelict building. Part of the reason we had to go was we stopped the ownership from doing things like holding raves. Over the most recent 6 years so little progress has been made to restore or make it safe. 210

David Booth @caleydave.bsky.social · 15/09/2026Could be used as a case study on how to bury a story about operating without a Public Entertainment Licence or Alcohol Licence. If the other safety concern had been run the headline would be "In Bizarre fire exit dispute"! 141

David Booth @caleydave.bsky.social · 12/09/2026If the old Caledonian railway via Roseburn was reinstated or the South Sub converted it's strange to think that could visit a station some ~70 years after he worked their and some ~60 years after they closed. 020

David Booth @caleydave.bsky.social · 05/09/2026Such is the attention to detail, and not always demonstrated on tours, Messages from the CCP to the Carrier Receiver also activates the one in the operations room. And, staying in the operations room, the telephone on the Warning Teams desk can speak to the demonstration CCP. 000

David Booth @caleydave.bsky.social · 05/09/2026I believe there are a few tickets left! Relevant to #SirenSaturday , The Bunker housed the Sector Controller for Scotland, who should national communications fail, be responsible for issuing warnings and 28 Groups who's warning team would be in direct contact with the Police for issuing warnings. 110
