Birmingham BT EXCHANGE BUNKER Lydon Green
Вставка
- Опубліковано 12 гру 2023
- Known to BT as Lyndon Green TRS (telephone repeater station) or Birmingham/G, this building is one of the handful of protected repeater stations constructed during the Cold War period. Its life as a functioning BT building had ceased.
Lyndon Green was known technically as a PR1 (protected repeater station, type 1), comprising a two-level bunker with heavy blast doors. It is semi-sunken, with the main distribution frame and active equipment on the ground floor and power plant and ventilation system in the basement below ground.
It is located in an island site between the Coventry and New Coventry Roads at Sheldon, where the west and eastbound carriageways of the A45 road diverge, some distance south-east of the locality known as Lyndon Green. The postal address is 53 New Coventry Road but there are gates into the repeater station yard from both roads.
Repeater stations were locations where the signals on telephone cables were amplified to counteract the electrical losses that tend to make speech fainter. The majority of repeater stations were located at intermediate places between telephone exchanges. Lyndon Green is on one of the main trunk telephone (and television) cable routes between London and Birmingham, having a number of important circuits passing through it. It was constructed at a time when all repeaters (amplifiers) used thermionic valves (vacuum tubes), which required far more electrical power than the solid-state amplifiers of today. Accordingly the repeater station had a substantial power plant, with its own electricity substation, a large generator (removed some years ago) and storage batteries. The station had equipment stores, a test desk, repair workshop and eating/recreation facilities.

It seems BT remove all their old crap, unlike the MOD that leave everything to rot!
Nice one mate! 😎👍
Watching from America 🇺🇸. Former Navy here, I remember buildings with them air old handler units. I was medical and closed two old Naval hospitals in my day. Lots of cool places to explore on old bases.
These protected exchanges were constructed in the suburbs and all over the country, about 10% were considered strategic exchanges, built to protect the national trunk network alongside the GPO / telecoms bunkers in Glasgow, Manchester, Birmingham and London. This one is up the road from where I was born, my sister in law worked there for BT, I'd no idea it was still there.
Don't be daft! Glasgow gpo bunker is just a myth and that's all it is. Bath Street indeed has a cable tunnel but that's all it is.
The boreholes were sank and the site never completed.
I work in cable tv and telecommunications. In the manholes we use those inflatable plastic bags to seal the duct or cutout hole to stop water or gases from escaping into the other area. Some of them are fire resistant as well. They use a little co2 cartridge to expand them
wow, thanks for that info
The weird spring loaded locks are called a castell key system
You have 1 master key locking in a load off slave keys which are coded to the locks
I use them in work matt 👍
Omg it's so big it's good you show as what these places are like 👏👏👏👏Matt
I had a Lady-friend who worked in the most restricted part of that place, she often said the most exciting time was when they had fire drill and all the nice firemen had to evacuate the girls.
Thanks for your effort matt keep them coming
Thanks, Matt, that was a nice look around!
only just seen ,matt but this is a so so good find, the best i would so of loved to bin here with you, 👍🙏
It was once such a beautiful place. Thanks for the old photos
Loving the picture quality another great explore
Have you ever managed to infiltrate the tunnel network under what was Longbridge car factory in Birmingham?
It was burrowed into the nearby Lickey Hills and was I believed used to protect workers and stores during the wartime bombing raids in the 40’s but may be older than that.
Back in 72 I was 16 and just started work as an apprentice for an electrical contracting company there and we had our stores down there as did many other contractors. Dark scary place. They were partially walled off though. I worked there for 18 months and hated going to the “stores”.
Its reputed when the new owners bought the site (then MG) they had the tunnels investigated and discovered perfectly preserved cars and equipment!
this place has been cleared out no end, they did a sweep on it around 3 years ago, i visited in 2016 i think, there were still a fair few relics around.
ik it’s a bit late but where exactly is this me and my mates wanna go have a look around?
Interesting Matthew Cheers Thank you very much
Smashing, love it when you go underground
Nice one Matt 👍🏻
Hi Matthew. Nice to see your still managing to infiltrate BT places. Hoping you manage to get into some places that still got some of the cream coloured metalwork, add seen in Nick Catfotds photos. I think Theresa very big underground place in Birmingham and another in Manchester, on same lines as the famous place below High Holborn. Worth a visit if you can get in without falling foul of the old bill.
Also looking forward to some more of your military visits, where you can still see stuff inside. Favourites do far are Goat testing Gosport, (I went in two weeks after you btw).also the one where you took the dog in Cornwall near Newquay...
Look forward to anymore Military and GPO..
Keep Up ood work...
The “very big” place in Birmingham is probably the same one I’m thinking off called “Anchor”.
It allegedly linked banks, telecommunications and other utilities and important offices etc via a huge tunnel network.
I was told about it when I worked at Summer Lane, the former HQ of the Birmingham Electricity Corporation which later became Midlands Electricity Board (MEB) after nationalisation. (I worked at various MEB depots during my 40 yrs with them)
There was the entrance to the supposedly huge tunnel network under the offices there.
The tunnels still carry cables throughout the city centre today but were big enough to walk easily through and had other tunnels leading off them.
I love this bunker. Thank you!
Just wanted to thank you matt as I'm currently working but blurting out what the fox at any trying moment
You have this lasting affect on people 😂❤
Looking forward to this one.
Yeah, another great explore 👍
Hey Matt that's the same process that they for electroplating.. And they use that process in home ionizers. And in chrome dipping and powder coating..... Ect... The more you know. :). Troy
i heard a story that a group used that place as a illegal rave space back in the 90s ,how true anyones guess ,big space underground easy to get gennys lights and dj stuff in,,the bunker under the council city hall be a nice find ,
Epic!! 3:10 looks like the Squash Court from Hell!
You naughty boys great explore Matty.
Great video Matt! Love to buy that and turn it into my house 😂
Matt, that is exactly the same as the one on top of portstown Hill. But we couldn't get in. It is sadly the same no different.
Great video MATT
They normally have a big Rsj and a block and tackle to get the generators into the bunkers
Yesss finally a bunker video, bloody love these Matt
The thumbnail sold me dreams
Brilliant as always Matt. I'm surprised you don't find anyone living in these places. It definitely looks dry enough to live in. You should have nicked that Blue flashing light. It would be good in your car when these stupid security get too close when your doing these explores at these out of the way places. You could just blag your way out of trouble.
Fascinating is it all under the bt tower now?
yeah the BT Tower took over.
The stuff and tunnels under the BT tower is part of the “Anchor” network under the city centre.👍
strange the alarms seems to still be working or at least doing something anyway, more so the vandals have already got in there, and it still doing it's thing, that would suggest the powers still on, there maybe still plans for the building use for something a bit spooky that bit?
make an awsesome night club
Nice one matt peace out to 😅
Hey if anyone here in Birmingham on go by the courts you will see his pictures in a window
Can you imagine being locked in here and starving to death
one thing I will say is that place has one hell of an echo.
No Reinforced Autoclaved Aerated Concrete (RAAC) used.
Very similar to the BT Bunker on Portsdown hill Portsmouth.
Portsdown was gutted out by metal thieves in 2018 also not worth the effort.
@@RobDavis-in5mh Its actually in use by a company so not possible to go in and look.
@@TheSecretVault Yeah its in use but stripped from original features
Finally a bunker vid lol
Bob Head, I know his brother Richard.
Bob the keyholder is not answering.
Anyone know why the spellings on the sign are incorrect 'Exxchage' etc - is it some kind of security thing?
👍👍
Fair play wendals
Went here the other week and it was sealed
We know a few people who went in recently a few weeks ago. So you must have been unlucky. Not sure how long it will stay open.
👍🏻
💚🤙🏼♥
What is the date of the pictures with the equipment?
its all on Sub Brit website.
You ended it with the intro instead of the outro don't know if that was intended??
looks ok to me.
Went here years ago no graffiti back then such a shame it’s been tagged up 😮
Trespass
Lots of asbestos and lead paint in these old places, better wear a mask.
British bunkers are weird. It’s like a couple of brick layers slapped them together after hours as a cashie. It’s like they never had anyone serious build them.
another great explore matt
:)
Stripped out bunker not worth the effort in my opinion
I think most of em are going to be stripped out anyways. unless you get really lucky.
Probably correct very expensive
Effort of what mate?
@@scaleop4 Bud there not all stripped out. This one was attacked by metal thieves in 2016 hence why it is empty. Not worth visiting.
@@RobDavis-in5mh I still like his content and not every explore needs to be a 10, I still give this an 8 because, it's underground! 😊 Happy holidays! 🎄🧑🎄
What's the biggest takeaway here Matt needs to get a boyfriend that's a tagger. seems like everybody that has a spray can has been to this place to paint something. taggers seem to have all the information where these places are long before the Explorers know. it's obvious here that UA-cam creators will
put anything on the . was a total waste of time
errrrrm.
🥇
Interesting matt not much left in it when are you with plopeye again
hopefully soon. Check out the boat video.... its up for members at the moment.
