I worked in other sections of that subway, I had been in that tunnelling machine many times, it's the same one that drilled the section from Can Zam to La Sagrera stations, was disassembled there and carried to that part. Many of the tunnel sections you show (the ones vertically divided) are already finished, just waiting for the rails and the trains. However, the stations in that area had to be done after the tunnel passed, and the side of the tunnel disassembled to allow for the platforms to be constructed. In that part of the city, the works were stopped due to the "upper side" of the city filling complaints and threatening legal action for hypothetical damages to their homes, so the works were stopped more than 10 years ago and never resumed. There are talks to resume it, but many people living in the upper side care not for "peasant transportation", and will do whatever they can to stop it. The worst is that part of the construction cost for those projects was to be offset by selling the tunnelling machine after the project was finished. Being abandoned like this, the cost will have dropped dramatically, despite being a good machine back in the day. Bonus track: When I was in the other section in 2004, that same machine had to stop near the Fondo station due to sandy terrain. If the machine moved forward there was a high risk that a whole block would be swallowed by the tunnel. The machine was stopped and the terrain had to be stabilised by jet grouting (injecting concrete into the sand to make it solid, allowing the machine to continue excavating without risk of collapsing. The losses by the construction company (and, by extension, the government) were estimated in tens of millions in those 3-4 months the machine was stopped. Now it's been more than 10 years, so...

I worked on the Seattle tunnel project and this brings back memories. The boring machine we used was heavily computer controlled. The sensor monitor room was part of the machine, it was bigger than the one these guys found, it was sealed and on vibration mounts, you never could tell the machine was in operation, right adjacent to the computer room there was a clean break room and sleeping areas for 6 people. The rooms were divided 2 per partition. There was a shower, toilet, television with cable. They made us work 10 hour shifts even on Christmas, the logic was we couldn't refuse if we were already there. Just like this machine, there were crew safety bunkers for the construction crew and the computer staff was supposed to use the sleeping quarters as their bunker, I guess it would have worked it did have emergency air tanks on the back end. I remember coming out of there after 28 days, I would get headaches when outside, my eyes suffered temporary shock or something.

After it completed boring the tunnel and broke out into the disassembly vault, it was cut up into scrap metal for removal. It was built specifically for boring one tunnel, and there was no practical way that it could be reused anywhere else.

Typically those tunnels are made with 48 differently dimensioned concrete segments. They're gasketed and bolted together to do whatever routing needs to be done. I love tunnels. You can also find an abandoned 9 foot machine in Tacoma, WA....no doubt flooded. It got stuck and the French company abandoned it and went bankrupt because of it. That was for storm water drainage into Puget Sound. Each segment was 3 to 6 cubic yards of concrete. There were over 100,000 segments in each tunnel. 9 foot, 11 foot and 14 foot. 3 tunnels

@@shannonrickard8605 I imagine it has to do with safety and or there being a breach somewhere that allowed a lot of water into the tunnel. The cutter heads of tunnel boring machines are well ahead of the section that builds the concrete walls as it moves. And since those machines are really only designed to go forwards backing it out is impossible. The diameter of the boring machine is larger than the final diameter of a finished section of tunnel. Thus, the only way for it to come out backwards would be in pieces, which means you'd effectively have to destroy the front part of the machine to remove it. Costly, due to the labor involved, safety risks, and then the fact the machine itself is destroyed in the process.

@@randomman057 often when a projected is completed, another tunnel is constructed for the TBM to be entombed for eternity.

Never was, large scale projects take many years to complete. Misleading title.

[@yobb1n544]

@@ACombineSoldier I mean, even sitting idle is still a waste. Better get it finished asap so people can actually use it

[@EphemeralProductions]

@@yobb1n544 they’re fixin to do just that

It's not abandoned, it was temporarily paused because of the 2008 financial crisis... it has now been resumed

[@jlucasound]

This is a cool change of pace! Nice Find, Guys! It was wierd when Michael said, "In Case of Emergency, we're screwed". It sounded funny and then it hit me. He's not kidding! Now.... I know the odds of them experiencing an emergency are pretty slim, so I am sure they will be fine. Thanks Guys and be Safe!!

[@partyboy2991]

Hope you went back for your phone when it fell out @20:50 when you fell. But other than that, great exploration!

[@deranator2934]

man i wish when i was younger we had cell phones to record out adventures like this. Thanks for the entertainment boys and risking health and possible trouble with the law. god bless

[@kathylebro1359]

That was by far the coolest thing you guys have done. Great exploration!!

[@trevorharley4475]

That was an amazing adventure for me! I can't imagine how cool that must have been for y'all. Thank you for this. I really enjoy watching these videos. I really loved the metal gear solid style snaeking past the guards when the train rolled by. That was great.

[@quietusplus1221]

This has to be one of the most incredible spaces you guys have explored, just by sheer size.

[@MegidolErin]

I can't even describe it but this one was so good. The wind, the lighting, the big empty shots. It just feels so barren. Same vibes as URU if anyone remembers that game lmao

[@cosmos7492]

Enjoyed that thanks for taking us with you guys

[@brendawynkoop1735]

What an amazing experience for you all. It also was so interesting to me. Making that tunnel was not done as I thought. Very educational to me. Thanks for taking us along.

[@PlayingwithPawz]

Great content as always this looked like a cool one to explore i cant wait for more

[@bassfan71]

One of the most interesting explorations you guy's have done! Great to tag along watching in this video!

[@wes5150.]

I hope I don't have nightmares in my sleep being LOST in that tunnel. YIKES ! Thanks for another outstanding adventure !

[@sgs753]

What an awesome Lost Place!! Thanks for sharing it PP!! Greetings from Germany.

[@filanfyretracker]

I am amazed at how much lighting is active in an unused and unfinished tunnel.

[@MrSwampdawg47]

At 18:15 that’s a cat next gen excavator. Caterpillar came out with those in 2019-2020. Judging by the condition of the machine, it hasn’t been there very long…

[@cosmicshatter91]

1 of the best intros, I still can't get enough of the tune since they started using it..

[@mirandarosman3721]

Love you guys from Australia 🇦🇺 Always awesome content. Thankyou!🙏

[@XenoWiz]

Thank you guys for this I really enjoyed this I hadn't a clue machines was or could get that big. TYVM

[@jasons8479]

So nice of them to leave the lights on for you!

[@angryanubisart8893]

beautiful work. I love photography of these engineering sites. It is amazing what we are able to build and bore deep into the earth. its like a sci-fi movie

[@ipposaur]

I freaked myself out by imagining the sounds of the machine starting to come to life and fill the front bit with water when you went up there

[@barryf5479]

That machine had to make a LOT of noise when running.

[@mnitchman]

Wow! Enjoyed this one guys!!

30:36 - Missed opportunity for "Chairs just drilling".

[@P0LSKI]

Quite possibly, the coolest thing I've ever seen on KZbin! This was INCREDIBLE!!

[@WafflesASAP]

You guys are equal parts brave, curious, and crazy, lol. This was wild, man!

[@Megaultrastupid]

You guys are so underrated, I love the 4K cinematic shots you take of all the run down and abandoned places you’ve explored, and watching these videos is really surreal, you guys make me want to do this stuff myself lol.

[@davedennis6042]

I love those lights you guys use. They really bright and light up everything so your videos are interesting. The best news was at the end when you said they did start working on this again. What a remarkable feat of engineering!

[@radeemer1]

This felt like one of the most "URBAN" explores that The Proper People have done. I know they explore a lot of places in the middle of urban areas, but they always start after they are already in the building and the buildings are pretty much completely abandoned. With them climbing over fences and stuff in the middle of a city, the modern industrial equipment, the lights still on in the tunnel; it felt way more urban and suspenseful than most of their videos. I really love this video.

[@Jamie-hu8fq]

The barrels of grease will be for the main drive lubrication and tail skin sealing grease. Also the first part where you mention about making the machine move this was the grout tank and grout pumps which are use to seal behind the ring segments after they are built.

[@ashleybrooke2087]

I don't know what's more existentially saddening; an old abandoned site that is well past its better days & just left to decay or the wasted potential of some place that never fulfilled its intended purpose. To me, it's about all that energy & time that was put into something that now doesn't matter anymore.

[@ronsloan7662]

Great explore guys! We all know these tunnels are big but seeing you guys walking through it really puts it into perspective. Great video and as always look forward to your next one. Cheers!

[@colatf2]

It’s not really abandoned, more like idle or stalled. Some day, they may finish it

[@Rhewin]

It’s not abandoned. It was on hold but they’re starting it up again

[@ashleybrooke2087]

@@Rhewin That's good. It would just feel like a waste otherwise. I've read & seen things about projects here in the states where buildings never got finished or they did & now they just sit empty & useless

[@ashleybrooke2087]

@@colatf2 I hope so. I'd hate think all that effort went into something without completion.
