I've been bingin every video released, I'm trully amazed by both the quality of these productions as well as the engenuity/quality of the work done on the projects. I really wish my field of work aligned with Marti, seems like an amazing company to work at. Congratz!
Thank you for all your outstanding videos. I see the Easter block works seem a lot more "FRIENDLY" to filming them work, than the American Tunnel "HOGS" this is just amazing design of equipment and the workers knowing what they do.
It's kinda ironic to me that this takes them so long to do (and yes precision is for longevity) but then they have rails in Eastern Europe that are basically off roading for trains and they still work well enough...
Howdy, as a friend of an SBB employee and a Swiss citizen I cannot give you a definitive answer, but I can give you some general information: 1. Air quality has to be monitored in every workplace in Switzerland where there is a risk of having polluted air. This is a rule made by the SUVA, (Schweizerische Unfallversicherungsanstalt = Swiss Accident Insurance Fund) so it probably was obligatory. 2. Depending on the construction Site, Safety precautions and how close your work is to the trains, they are only permitted to drive by with speeds between 40 to 80 km/h (~25mph to ~50mph). In the video it looks rather like the lower. In Switzerland this is a speed at which you can "drive by sight", so i guess the train driver could spot obstacles himself and break soon enough. (Sorry for the spelling, grammarly had a seizure) have a nice one!
The concrete doesn't, however there are rubber pads under the rail and the rail its self is laid to a very high level of accuracy as to prevent vibrations and shock loads.
Though these people are exponentially smarter than I am, when all that new work reaches the end of it's service life, all that concrete is going to be a b*tch to remove. It's much easier to remove and replace ballast, especially in the cramped space inside the tunnel.

Marti seems to have an answer for every engineering challenge.
Did you also find the Ritom one first and then start watching a bunch of them?
@@jdmillar86 That’s me as well 😅, that Ritom video was just 🔥🔥
super cool. I love the creative solution with the monorail suspended from the ceiling, this never could have been done without it
it`s appropriate to say, Marti is the worlds best tunnel constructing company. 😀👍
As always, very impressive engineering work and equaly good animations and video overall. Thanks!

Fascinating to see that pretty much anything can be done! Nice engineering job!!!
Sincerely,
The single greatest ad dollar investment in history.
Before you’re last vid I’d never heard of Marti…lol
This is amazing engineering, especially the plannings. Salute to all men and women working this project. Such an eye opening.
Impressive work, this is how rail upgrades should be done, instead of shutting down traffic repeatedly for years.
Awesome commercial for the marti group.

Excellent stuff. Really innovative solutions here.
Thanks 💐💐
I just enjoy these videos
I hope they do a similar solution to the east and north river tunnels under New York
a lot easier to understand in English thankyou
Ingenious!
This is addictive
you guy are geniuses
I wonder how easy it will be to renovate all this concrete after 30 years.

balkan is just built different :D
Great video
2 questions
was the air quality monitored
was there an inspector checking for foreign material on the adjacent operational line

@@philippjorda4671 Thank you for replying
Carl at 9:49 would like to have a word with you.
Are the cross tie blocks rubber?
Super Unternehmen
how does the concreate absorb the vibrations?
The concrete doesn't, however there are rubber pads under the rail and the rail its self is laid to a very high level of accuracy as to prevent vibrations and shock loads.
Perfect!
Why didn't they just replace the rails? Do concrete sleepers sheltered in a tunnel degrade that much?
The concrete sleepers get strained by the trains going over them. With each train the sleeper flexes a tiny amount. Over time cracks form and grow.
I want to work at Marti

Wow geat company. Is it publicly traded?
does not look like it, website says family owned
Blausee?
ungehindert in Dietikon zu bauen 3 km der Straßenbahn bereits über anderthalb Jahre
Renoviert doch einfach den ganzen Tunnel und nicht dreiviertel, wir sind in der Schweiz. 🇨🇭
es wird ja die ganze fahrbahn renoviert?

Marti is the answer for all engineering problems 🫡
