Following on from the previous #SirenSaturday we have another building with no obvious remains of a Siren. "Portobello Indoor Baths, Melville Street, Portobello" This was given Carrier planning number 254/107 in the early 1960's.

Well 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 ?

Controversial statement; Vandalise your books! My Late Grandad was a Relief Clerk for British Railways around Edinburgh in the 1950's. I had taken on some of his books and in an appendix of this one he had marked every passenger station he worked with a tick and each Goods station with a G.

Cover of book: Rail centres: Edinburgh by A.J. Mullay

Appendix 1, this page has the first half of a list of stations in Edinburgh.

Stations marked with a tick are:
Abbeyhill, Balgreen Halt, Colinton, Corstorphine, Craigleith, Dalry Road, Gorgie East, Haymarket, Joppa & Leith North

Goods stations marked with a G: Bonnington Road, Currie, Gorgie East & Granton.

Appendix 1, this page has the second half of a list of stations in Edinburgh.

Stations marked with a tick are: Merchiston, Morningside Road, Piers hill, Portobello, Princes Street, Slateford & Waverley.

I can safely say I was not a fan of the seats on the sleeper, I did not sleep at all. I Came back the same (long) day on LNER pulling into Waverly 24hr after it left.

I knew I had a copy of the top down view and it was in a presentation. This is proposed, you can make out the Two quarries (and Tramway in the Worked one). As well as the water proofing, If anything is built on the hillside than loadings on that lump of concrete will need to be factored in.

Extract form a Diagram entitled:
"SITE MHA
SITE PLAN FOR STRUCTURE R4
Scale:- 1/500"

"Drawing No 3/23E

It shows the current layout of the two quarries with the proposed R4 overlaid.

Bingo, here is a better view of the steep hillside (it's worse than it looks). This was 2014 and the same day as the picture of the fire at the emergency exit. The emergency exit and air intake is left beside the fire, the cooler exhaust stack is right.

The picture is off the hillside covering the R4 at Barnton Quarry and is from 2014.
The emergency exit and air intake is left beside the fire. The fence to the left is the boundary with the council quarry. The cooler exhaust stack is right. Between these two stacks sits the plant room annex where the 'dirty' (radioactive or gas filled air) air handling equipment is located.

David Booth @caleydave.bsky.social · 02/08/2026

Here is the view of the hill following tree clearance. There was a lot of ash dieback which had not been dealt with due to being on private land. I would hope despite looking drastic it would have helped the nature reserve. Where I was standing is what has been dug up. That is the air exhaust.

The Barnton Quarry Restoration Project undertook work to remove the self seeded and non native trees. This was prioritised due to fears that the tree roots, due to their age, would damage the tanking. That knowledge was lost when the Restoration project was shuttered but also enabled this digging.

David Booth @caleydave.bsky.social · 02/08/2026

Now here is the issue, the new hill rises slightly between the cliff face & the air exhaust after which there is a steep hill down towards the cooler exhaust before an extreme, unwalkable, gradient down towards the emergency exit which is as close to the boundary fence as practical.

David Booth @caleydave.bsky.social · 02/08/2026

Instead Barnton Quarry (North) was leased from the Edinburgh Corporation, ending working at the Quarry, and the New R4 was built on the deeper Quarry floor. The only digging done was the circular tunnel section between the Quarries to link old and new buildings. The R4 was then covered with Shale.

David Booth @caleydave.bsky.social · 02/08/2026

In the 1950's it was decided a new underground Sector Operations Centre would be built to a standard design known as an "R4". The existing Quarry was considered but the hard Dolerite prevented digging and the backfill and landscaping would be massive to cover the 3 story Concrete block.

It is 3 stories with a rear plant annex and entrance tunnel either side.

The diagram recommends 10 foot of backfill on top.

In WW2 Mount Quarry was leased by the RAF for the Fighter command 'Turnhouse' Sector Operations Room. By war-end it was the "Midlothian" but in reality covered Southern Scotland. Following a brief closure when the Air Defence over Scotland was withdrawn it would be reactivated for the Cold War.

The name Barnton comes from the ownership by said estate and not the location. There are two Dolerite Quarries back to back. The Original Barnton Quarry, later renamed South then Mount, was worked until 1914. The Northern Quarry started later and was worked until 1951.

And if Nature and wildlife is your thing this is the current view on google maps. This is on top of the bunker. (The cooling stack is in the middle) of the cleared area. If they hit the roof of the R4 this it becomes a multimillion pound damp problem. Corstorphine Hill is a Nature Reserve.

As we watch parts of the Country Burn with increasing frequency is it worth the lament that there was once a supply of Pumps kept in reserve &, going back further still, Trained Volunteers to Operate them? With climate change & war fears accelerating when do we expand our underfunded Fire Brigades?

A page from a 1960's Civil Defence recruiting booklet.
It reads:
"Auxiliary Fire Service"
"saving lives and homes from fire is humane work. In the nuclear age, it is also a scientific job, because fire-fighting is a science, a highly skilled one. In the A.F.S. you are taught to fight fires by the most modern methods, and with the most modern equipment, some of it designed especially for nuclear war."

And that is the end of Radio 4 on Long wave 198kHz. 0100 AM 27/06/2026. The final normal program was the shipping Forecast. A short tribute to Long Wave was broadcast before the British National Anthem. Service has been replaced with a repeating message with alternative ways to listen.

David Booth @caleydave.bsky.social · 26/06/2026

The 1975 Edition of the "BBC WAR BOOK" suggests that Long Wave was not part of the War Time Broadcasting System (WTBS). Instead it was to be shut down and kept in readiness for possible special use.

Extract from the BBC 1975 "War Book":

Droitwich Long-wave Transmitter.
17. The need for civil defence regional broadcasting has reduced the value of the Droitwich Long-wave transmitter, as this cannot be regionalised. It is obviously important that nothing should be radiated which would divert the attention of the public from listening to their own regional transmissions on their own wavelength. The Long-wave transmitter will, therefore, close down when the WTBS starts, but will remain available for subsequent use if required. During the preceding hour, however, it will broadcast a special programme describing the WTBS, and informing listeners in the different Civil Defence Regions of the frequencies on which these regional broadcasts may be received.
