AT&T old Long Lines site. Was designed to survive a 20 megaton explosion at 2 miles. Its solid reinforced concrete with air filtration systems, blast doors, blast valves and air filtering and had its own power plant, its own wells etc. And held part of the underground communications systems that AT&T maintained for DOD. Started shutting them down in the late 80's as fiber optics became primary long haul communications instead of microware relays and buried copper cables. AT&T built over 150 of them. They were called Main Station Sites. The outside had an intake port for air that had blast valves and filters and an exhaust port for the generators exhaust. Most also had a nuclear blast detector in the form of a gamma ray detector that would report any nearby nuclear detonations, AT&T closed them down and sold them to private parties. There are still some on the market today.

[@magnuspitruzelli]

Do you have a list of the sites and contact information?

[@regandunn4850]

I want one lol

[@Johnclark300]

Good Idea to buy one now we don't when the United States is going to war with Russia. Russia is going to invade Ukraine real soon might want to buy it and get it operational before the great and terrible war starts nato will fight along side the U.S. and great Britain.

[@couchpotatoexplorationadve9197]

This bunker is actually for sale at the moment the owner is asking 350k I believe.

It makes me sad to see how vandals and thieves have destroyed this site with total disrespect for a historical site! I remember how it looked in better days, when my dad and I visited it back in 1978. My dad worked for PT&T and then AT&T, this was a L3 carrier main repeater station called Beacon underground, which was part of a buried coast to coast coaxial cable route. It was owned and operated by Pacific Telephone until 1/1/84, then it became part of AT&T Long Lines. In the main equipment room was bays of amplifiers, regulators, and equalizers. There was also LMX2 bays (multiplexing equipment), channel banks and group modulators. The bottom of the bays were mounted on springs! L3 cxr allowed for up to 1860 long distance phone calls on one pair of coaxial "tubes" ! I really miss those days, it was all so amazingly complex and interesting! All of this old technology has been replaced by fiber optic cables. And it breaks my heart to see how evil people have destroyed this bit of history! These main repeaters were spaced about 100 miles apart, with Mojave main repeater to the west, and Kingman main repeater to the east.

[@couchpotatoexplorationadve9197]

That’s awesome that you got to see this place in its prime! Do you know if the kingman site is still intact? This site in the Mojave is actually up for sale now hopefully someone comes and rescues it. Thank you for all your knowledge you shared on n here.

[@itz_mxxri]

Kingman, AZ is a toll central office and is still being used by AT&T for the fiber optic cable route. I don't know the status of the underground Mojave main repeater. It used to manned 24/7, and it had a microwave radio terminal also. All the microwave sites have been shut down also and sold to American Tower Corp. Back in the 70's, my dad maintained many of those auxiliary repeaters from San Bernardino to Mojave. They were smaller "huts" every 4 miles between the main repeaters. The next main repeater east of Kingman was Seligman. Since my dad retired from AT&T, we moved away from San Bernardino county. But for the first half of my life, that desert was my backyard, and I knew every microwave relay station and repeater station in the area. By 1992, fiber optic cables replaced all it!

[@miketibor6019]

This site was actually Baker, not Beacon.

[@itz_mxxri]

@miketibor6019, I know, but the comm. techs of PT&T called it Beacon underground.

[@jacob3432able]

This at&t long lines repeater was intact up until earlier this year when it was stripped for copper by thieves. The insanity of stripping 1k of copper from a 100k turbine generator still gets me. the owner like most, wanted too much for it and this is what the result of it sitting is.

[@couchpotatoexplorationadve9197]

Wow that’s crazy looked like it would have been a awesome building to own. But yes from what I could see anything electrical was stripped. Kinda sad how vandals destroy these sites.

[@Britcarjunkie]

What's funny is, there's areas in the desert where I used to go off-roading around there, and the ground had eroded so much in areas, that the underground phone cables were sitting on the surface, and we'd run them over, because they wan along the trail - and this was while they were still in service!!!

[@miketibor6019]

At 12:55 or so, you comment on a gray thing mounted on top of a 3 ft or so diameter concrete pedestal, and you question if it might be an air vent. That's a gamma ray detector. It used a piece of film that would melt when bombarded with gamma rays. That piece of film was mounted between two electrical contacts. When hit with gamma rays, the film would melt, the contacts would close and trip an alarm in the station. Usually this was used with one or two other detectors--a light meter (detecting the flash of a nuclear detonation), and/or an atmospheric overpressure sensor. A lot of times though, just the gamma ray detector was used by itself.

[@kevin2960]

Yep definitely a AT&T bunker. Been in one of these that was my intact

[@skeets6060]

MY GAWD does that bring back memories,,, I worked for WE, and these main buildings, and the long line building were the place to be if shit went sideways. The food storage was insane, any and everything you could want or need to survive. I wish I could find one of those abandoned places for cheep

[@itz_mxxri]

I appreciate all the hard work you Western Electric guys did back in the day! It was truly a work of art the way all the equipment was installed! I remember watching you guys work, when I visited the toll office my dad worked at for PT&T and later AT&T. It's such a shame to see all your hard work destroyed like this!! These people are evil!!

[@grampabadger]

Old AT&T Long Lines site. Some still exist on private property outside Pueblo, Colorado south of Ft. Carson Army base. Old towers removed a number of years ago.

[@wes11bravo]

When these sites were built, money was no object. There's a bunker like this about 30 miles north of me and one of the Long Lines tower sites is just over the hill from where I live. Made to withstand a close nuclear detonation. Most of the old Long Lines sites around here are now owned by American Tower.

[@couchpotatoexplorationadve9197]

What area are you in? I’ve heard these kind of bunkers are all over Southern California. Definitely interesting most of them are private owned but always awesome to get the opportunity to explore them.

[@johnnyrebel3340]

​@@couchpotatoexplorationadve9197 The problem is people. Putting this info on blast only spells doom for decommissioned sites. Needless to say. Great places to hull up in a hard push.

[@traviskisner2275]

I love the Trane Compressor!

[@Acoustic_Theory]

3:30 - On the far wall is a sewage ejector pump system. Sewage enters from the sides and exits on top. There are two motors visible on top later. Normally the sump is buried in concrete so it can be the lowest point in a structure but here it is above the floor. Also there are spring isolation bases under everything that look like they are intended to keep equipment safe from seismic activity. The large white tank is compressed air, I think. So maybe the isolation bases are there to keep air compressor operation from vibrating the floor, but the compressors are gone.

[@craigs.546]

That is a neat place! They could of disguised it as randomly closed convience store that I know and people would be none the wiser. Lol :)

[@svkiion]

wow

[@Acoustic_Theory]

2:10 - These are blowers for fresh air intake or some other kind of HVAC air handling. The round plates seen earlier that were over duct openings in the wall were for air supply, and the doors can be closed remotely, probably by the air pressure stored in the big pressure tank seen later around 3:30.

[@kitchenengineer1731]

Damn dude, slow down with the camera. I'm an engineer and I'm trying to deduce what all this machinery is. Spend a second or two on it. Maybe I'll drive out there in the a.m. and check it out.

[@garyf8229]

It’s an old AT&T long lines site. Several thousand were built during the Cold War. There was originally a microwave tower above ground.

[@itz_mxxri]

No, this was not a microwave repeater station, this was a main repeater for L3 carrier that operated on buried coaxial cable that could carry thousands of long distance telephone calls. It ran coast to coast, and we're about 100 miles apart, with smaller auxiliary repeaters in between. Mojave was the main repeater west of it, and Kingman was the main repeater east of it. It was owned and operated by Pacific Telephone, until 1984, when it became part of AT&T Long Lines. My dad worked for the Bell System and he and I visited this site back in 1978.

[@Acoustic_Theory]

4:30 - That's similar to the generator that was at another of the AT&T Long Lines bunkers in another video; the generator is a Detroit Diesel 12V71. Lots of old package air conditioners. After 4:45 in the next room you're looking at the fuel tank for the generator with two fuel pump motors on top.
