3D animation TBM S574 "Martina" (eng) 

You should see the engineering behind JR-Maglev L0-Series then.

@@nuduw Can this machine turn or only go in a straight line? I'm confused because the map shows a tunnel that is non linear.

Hope it wasn't made in Italy. Everything they make breaks alot.

Different models of TBM may sometimes have different features incorporated depending on the conditions it will be working with. I.E. undersea ones like those used in the Big Dig had special waterproof outter shields. Then the ones that work in more unstable or softer ground often have reinforced hulls or internal supports to minimize the risk of cave-ins.

@@terminalvelocityrunner2202 how are the turns made? I'm confused because the map shows a non linear tunnel.

4:46 You can see the head of the TBM being pushed away from the concrete "tunnel" construction. They use electricial driven pistons for it. Also 9:18

sjorsbeans Ooh, thanks! Completely missed that detail.

No, they use láser guides

Claro soy tunelero y la tuneladora tiene articulación para girar ala izquierda o derecha

*what the hell for?*

I highly doubt that. They would have used that in Seattle instead of Bertha. Secondly, shifting ground, floods, cave-ins, and other risk factors would make nuclear powered digging machines into literal death traps. If one was to explode or malfunction in a variety of ways, it would explode like an atomic bomb. Then there’s the fact that, oh, I don’t know, it would make national news as the first of its kind as most, if not all TBMs before it used onboard generators so as not to polite the tunnel’s air supply. So that’s some pretty big talk coming from someone who doesn’t even have a profile pic after three years. Edit: Oh, I’m sorry, no profile pic, not a single upload, and two subscribers that are likely people who you asked to do so IRL after at the very least three years.

i am tunnal master call me
