As Metrolinx is preparing to embark on digging the single-largest subway tunnel in Toronto's 67-year history of rapid transit, the 7.8-kilometre Scarborough Subway Extension, the Herrenknecht Tunnel Boring Machine is being shipped from its factory in Germany.

The 7.8 km extension, being built by Austria's STRABAG, which will run underground for its entire length, will connect the existing terminus at Kennedy Station with Sheppard Avenue/McCowan Road. The contract includes one launch shaft, one extraction shaft, five headwalls for future stations and 14 headwalls for future emergency evacuation buildings. The tunnelling works will be performed using a TBM with a diameter of 11.87 m.

And the TBM is being literally shipped:
