Mining, not boring.

This very large dinky toy arrived this week on LeBreton Flats at the Confederation Line LRT tunnel entrance.

It is like a front end loader, but photoshop compressed, flattened out. It will be used when the contractors “mine out” the tunnel. They will be drilling into the tunnel face and removing the debris with this loader.

During the planning phases of the LRT, City staff and consultants talked about using a boring machine to dig into the rock face. But the winning proposal used mining techniques.

The smooth tires is a bit of a surprise. They seem way too smooth for the heavy task at hand.
