More boring transit news: "Yorkie" and "Torkie" cross Jane



TTC and City of Toronto contractors continue to workg on the project to extend the Spadina branch of the 1 Yonge - University - Spadina subway northwest beyond Downsview Station to Vaughan.

The two tunnel boring machines or “TBMs”, “Yorkie” and “Torkie” recently passed a milestone in their job to dig the tunnels for the new subway by crossing under Jane Street. Since they left their launch shaft near the future Highway 407 Station site, they’ve been heading toward the extraction shaft near the future Black Creek Pioneer Village Station. The extraction shaft is north of Steeles Avenue West at the north end of York University’s Keele campus.

“Yorkie” and “Torkie” will both tunnel about 945 metres in this drive and place around 1,262 liners in the tunnel.

The contractors expect “Torkie” to arrive at the extraction shaft in early June, while “Yorkie” arrives later that month.

The TTC dubbed the four tunnel-boring machines for this project “Holey”, “Moley”, “Torkie” and “Yorkie” after a public contest to name the machines.
