What Toronto's giant tunnel boring machines look like

Fans of heavy machinery and transit nerds got a treat this weekend as Metrolinx extracted and re-installed its two massive tunnel boring machines, Dennis and Lea. The operation brought out over a hundred people (many of them photographers) curious to see what these technological beasts look like in person.

The process was a slow one (what do you expect with 400 tonne objects?), but was ultimately a success as both tunnel boring machines were reinserted into the earth just to the east of Allen Road, where they will now continue to lay the groundwork for the Eglinton Crosstown LRT.

An opening date for the new LRT line is still years away, but this weekend was a reminder (over and above traffic delays on Eglinton) that the project is coming along. Check out photos of the big move below.
