Four boring machines started work Friday morning at Sheppard Avenue West station.
Named Holey, Moley, Torkie and Yorkie, the four tunnellers began drilling their 8.6km way northwards in the latest extension of the city's subway system, connecting the
Spadina line to York University.
The project, which will add six new stops to the line, is estimated to ultimately cost $2.6 billion.
According to Dale Albers, York Region Rapid Transit Corporation's communications guy, "Work started at 10am and will go on 10 hours a day" until the tunnel's finished. The borers place the tunnel liner down as it digs, building the tunnel as it goes, according to Albers.
The project is scheduled to be completed in 2015.
