Holey and Moley Make Project History!
On June 11, 2012 the Honourable Julian Fantino, Minister of International Cooperation and Member of Parliament for Vaughan; His Worship Rob Ford, Mayor of Toronto; York Region Chairman and CEO Bill Fisch and Toronto Transit Commission Chair Karen Stintz joined special guests and the media at a site adjacent to the future Sheppard West Station to celebrate and mark an important tunnelling milestone for the Toronto-York Spadina Subway Extension Project the completion of the first segment of twin tunnels.

Tunnel boring machine (TBM) “Holey” broke through the headwall at the Keele Street extraction shaft on May 1, 2012. A little more than a month later, “Moley” joined “Holey” and completed the adjacent twin tunnel, breaking through on June 4, 2012. “Holey” and “Moley” completed in total 1.6 kilometres of twin tunnels. This breakthrough marks the first major step toward the extension of the Yonge-University-Spadina Subway line through York University and the City of Vaughan.

Last summer “Holey” and “Moley” were disassembled and moved to the next launch shaft at the east end of Sheppard West Station where they are on the move, tunnelling east toward Downsview Station. “Holey” and “Moley” will each bore 1.2 kilometres on this drive. It is expected that “Holey” and “Moley” will arrive at the extraction shaft at Allen Road, just north of Sheppard Avenue West early in the New Year.

“Yorkie” and “Torkie” are boring the northern tunnels for the project. Both machines have successfully completed their drives underneath York University buildings and made excellent progress in their drive toward the Keele Street extraction shaft. “Yorkie” and “Torkie” arrived at the Keele Street extraction shaft on Thursday, November 29, 2012. They are now being disassembled and transported up to the Highway 407 launch shaft where they will commence boring activities southbound toward the Steeles West Station extraction site.
“Holey,” “Moley,” “Yorkie” and “Torkie” are the official names of the machines that are boring the tunnels for the TYSSE project. These names were chosen as part of a public naming contest. The TBMs will be used to build a total of
6.7 kilometres of twin tunnels.

Meet Our Tunnelling Experts!

Toronto is the new home for two Assistant Construction Site Managers tasked with overseeing the tunnelling operations of the Toronto-York Spadina Subway Extension on behalf of TTC.
“We love it here!” explained John Brown and David Urwin, both originally from England. John is leading the project for the southern tunnels; David for the northern tunnels. They are responsible for keeping their respective projects on time and on budget.
“It was pure luck,” David said of his move to Toronto. “Cities can’t sustain tunnelling projects for very long, so you tend to move around with demand.” David had worked in the United Kingdom, United States and Australia, before coming to work in Toronto.
John had just completed a tunnel project in Australia when he discovered the job in Canada. “Australia, as great as it might be, is on the other side of the world. Toronto, being closer to the East Coast, is only seven hours from London, so the proximity was definitely a draw.” There were other advantages, too. “I love checking out a ball game or soccer match,” John explained. “I had no idea the summers here were so hot!” Toronto, boasting its hottest year on record, has made tunnelling easier for the duo, who are used to working in warmer climates. However, you can always expect the unexpected when navigating a new environment. David and John got their first lesson working a few cold nights last winter. Equipment that had been sitting outside needed to be warmed in a heating tent before installation. “That’s something we’ve never seen before,” said David. Along with the environment, working with existing client’s infrastructure can also be challenging. David and John manage a team of inspectors, engineers, tunnel managers and designers who survey the sites before, during, and after tunnelling.
Four tunnel boring machines (TBMs) are required to complete the massive project. Each machine drills an average of 15 metres per day. In a tradition carried on throughout the world, TBMs are often named before drilling begins, as a sign of good luck for the project ahead. The TTC held a contest and selected “Holey,” “Moley” and “Yorkie,” “Torkie” a nod to the long-awaited transit expansion from Toronto into York Region. John thought the names were “quite reasonable,” compared to others he’s worked with. “I was on a project building a sewer tunnel in Melbourne, Australia and that machine was called Lucy Loo!” John laughed.
Once the tunnelling is completed, David and John will hand their work to a new construction manager, who will oversee track and signal installation. “Hopefully, the Toronto-York Spadina Subway Extension won’t be the last tunnelling project that we do in Toronto,” said John, reaffirming his love for the city.
Great Destinations Along the Way
Once it’s generally agreed where a subway needs to go, many factors influence which path it will take. Geology, budget, engineering, and destinations are just a few. The last one, destinations, is likely the most interesting for future passengers.
The Toronto-York Spadina Subway Extension will stop at the new stations of Sheppard West, Finch West, York University, Steeles West, Highway 407 and Vaughan Metropolitan Centre (north of Highway 7). This subway extension will bring fast, convenient access to those who work and live in these areas and to those who visit.
The new Sheppard West Station will be a neighbour to both Downsview Park and Downsview Airport (YZD). Join a sports league or go to a concert or free movie under the stars at the park, or even learn to fly at the airport.

Near the Finch West, York University and Steeles West Stations, Black Creek Pioneer Village will provide an escape from the modern world to a typical community found in the Toronto area during the 19th century. Associated with the pursuit of higher education, nearby York University is also a destination for concerts and sports events and has a vibrant social scene. For the more than 60,000 students and faculty travelling to and from York’s campuses in the GTA, riding the subway will be the smart choice. The Keele/Finch area has many schools and small businesses, and residents are sure to make use of a new subway.

The Highway 407 and Vaughan Metropolitan Centre Stations will serve as gateways to other destinations within York Region. North of Highway 7, Vaughan Mills outlet mall offers shopping, dining and entertainment and Canada’s Wonderland is an amusement park not to be missed. The Vaughan Metropolitan Centre Station will be surrounded by attractive, pedestrian-friendly spaces with great shopping, restaurants and entertainment.
Building transit means we’re building connections to where people live, to workplaces and education, and to exciting destinations along the way.
Community Project Office Opening in Vaughan
A new project information offi ce will be opening soon in the City of Vaughan, to be shared by the Toronto-York Spadina Subway Extension project and the vivaNext Bus Rapid Transit (BRT) rapidway project along Highway 7.
Residents and businesses are invited to visit the office to see visuals of each project and talk to project staff about construction. The location will be at 7800 Jane Street (northwest corner of Jane Street and Highway 7 West), near the future subway station, rapidway station and bus terminal.
The new office will be in the Vaughan Metropolitan Centre (VMC) development area, which will be busy over the next few years. Construction is underway to build the VMC Subway Station, and work is about to start on the Highway 7 rapidway - dedicated lanes for viva rapid transit. The rapidway will extend 3.5 kilometres from Interchange Way/Edgeley Boulevard to just east of Keele Street at Bowes Road. Near Jane Street, transit will connect with a combination of the subway station, a BRT rapidway station, and an inter-regional bus terminal - all within walking distance. Each project is funded and built separately, and together they’ll create an important hub for transit in southern Ontario.

The key to successful transit is to make important connections. By linking Toronto and York Region with convenient, efficient transit, we’re improving the transit network across the Greater Toronto Area.
- The first modern transit tunnel was built under the River Thames in London, England beginning in 1825.
- Toronto’s Yonge subway was the very first subway line built in Canada constructed between 1949 and 1954.
- Tunnel boring machines (TBMs) “Holey,” “Moley,” “Yorkie” and “Torkie” were built by Caterpillar Tunneling Canada Corporation (formerly Lovat) at a cost of roughly $15 million each.
- TBMs can remove as much as 15 tonnes of dirt per minute, rotating the cutting head with teeth in a circular arc, about six metres in diameter. TBMs can grind through clay, sand and rock.
- TBMs build the subway tunnels as they move along. Pieces of curved pre-built concrete tunnel liners, like giant Lego, are snapped into place as the machine moves through the earth.
- When the boring is done, the tunnel is finished, with only the track and internal utilities to be added.
