Niagara Tunnel Speeding Up

Reference

Yeah! The fever has broken! The tunnel boring machine is starting to chug at 6 m/day and only 3 m overbreak. I don't know what the 'Grout Tunnel' is, but that's starting as well.

Perhaps it won't get stuck now, as it runs for the surface. We just need everybody to be a bit more truthful on what all this overbreak means.
