Not only are they built for a specific tunnel, they're scrapped at the
completion of the tunnel.

I went on a geological field trip to Yucca Mountain, NV a few years
ago. *The tunnelling machine used to drill the nuclear repository is

When the TBM's that bored the "Chunnel" were done, they just drilled
