In order to excavate the high-speed rail tunnels beneath West London, HS2 is providing the way for the TBMs in West Ruislip. Currently, the West Ruislip portal hosts the giant cutterheads, which are part of the first pair of TBMs that are due to digging the tunnels.
The work process, the scale of the giant machines, and the various set of skills that are needed to work on the project are accessible here.
