Niagara Tunnel and Sandstone


Yeah, they're releasing information again! Must have been my complaints. :) Or they just could've put in another update regardless.

Although the script says the overbreak has reduced, it's still at about 3 metres, which is a lot. And I'm fascinated why they hovered just under the sandstone, rather than going up and watch the cutters getting instantly ground out. All in all, very interesting.
