  Quite an impressive tunnel.
  
  After 14 years of construction work, the 57km (35 mile) Gotthard rail tunnel is not expected to open until at least the end of 2016.

  I love the way they can tunnel from two sides so far apart and meet up with such accuracy. In this case the deviation was 8 cm horizontally and 1 cm vertically. Scary accuracy !

  Yes, very impressive but a bit OTT to knock an hour and a half off a journey!

  Sorry, can't be bothered to look.
  
  I've had enough of drills & tunnels this week.
