Tunnels Supplement

I didn't catch it while focusing on the British elections, but two days ago tunnelers reached hands after holing through the Guadarrama tunnel in Spain, which will be the fourth longest in the world when high-speed trains start to whiz through it in two years' time.

(pdf link in Spanish; I note they err when calling it the fifth longest - possibly they count the Gotthard Base Tunnel, which won't open until 2015)
