Tunnel boring machine naming for Scarborough Subway Extension & Eglinton Crosstown West Extension

First names released in subway tunnel boring machines contest

Vote for your favourite from a shortlist of names for the tunnel boring machines for two projects.

Dec 1, 2021

Metrolinx is asking residents to help name a big part of Toronto transit history.

What’s so big about? How about thousands of tonnes of tunnel digging power.

After a successful launch, the transit agency is kicking-off the next phase of the tunnel boring machine contest and inviting the community to vote on a shortlist of names picked by the contests’ judging panels.

Before we get to that, here’s a quick recap on how the first phase of the naming contest went.

Last month, communities along the Scarborough Subway Extension and Eglinton Crosstown West Extension were invited to submit names for the newest members of the Metrolinx tunnel boring machine family.

Over 340 submissions were received for both projects during the first phase of the contest, which closed on Nov. 19.

The shortlists

The entries were judged based on originality, connection to the community and relevance to the project.

“It’s really amazing to see the response from the community – not just how many people took the time to submit their ideas, but also how thoughtful the submissions are and how many of the names were so connected to their respective communities in Scarborough, Etobicoke and Mississauga,” said David Jang, Chief Communications Officer at Metrolinx.

“It just shows how important transit is to these communities. Of course, there were a few variations of Borey McBoreface and Tunnel McTunnelface submitted, so it’s good to see that people were also having some fun with the contests as well.”

Voting is open until Dec. 22, 2021.

Where are they now?

When we last saw these giant machines, they were undergoing testing at the factory in Germany. Fun fact: the tunnel boring machines for the Scarborough Subway Extension and Eglinton Crosstown West Extension were built at the same factory.

But in order to ship them across the Atlantic Ocean, they need to be disassembled into pieces and then rebuilt once they arrive at the tunnel launch sites. All three TBMs have left Europe and have started their voyages to their respective launch shaft sites.

One massive tunnel boring machine will be arriving for Scarborough’s single tunnel subway and two machines will be arriving to dig the twin tunnels for the Eglinton Crosstown West Extension.
