TBM cutterhead is being lowered into position today. Quality not so great due to very windy conditions.

Somehow those distance shots make it seem (to me) that the drill head is made of LEGO

I would love to see a video showing exactly how the drill head cuts through the rock.

...I presume most of the rock that this thing will be cut through will be shale?

Very impressive and expensive looking machinery/devices. Are those tunnel 'borers' from Europe or elsewhere? I wonder how they are powered. Diesel?

Yes, its going predominantly through Georgian Bay Shale. In contrast the Pape TBMs will be above the bedrock and will go through a whole plethora of materials.

Primarily powered by electricity - high-voltage cables feed the machine the power from somewhere on the surface.

...I would prefer dilithium crystals, but we're a few centuries away from that I am afraid. And this project will be taking long enough without having to wait for that. >.<
