Congratulations, Elizabeth!

Why do I find tunnels fascinating?  Is it because I remember digging through stuff as a little boy?  Or perhaps that I take the tube into work every day?  In any case, we just want to salute the 1,000-tonne tunneling machine nicknamed Elizabeth, which just broke through to the Liverpool Street Crossrail station 40 meters below the financial district.  Elizabeth is almost done, with only 750 meters to bore through for a 8.3-km stretch from Canning Town to Farrington.  The tunneling machine is quite a tribute to mankind’s ingenuity, not to mention the possible inspiration for some horror movies.
