		It is more than double the length of any previous tunnel ever built.
		In 1861, after three years of tedious hand-boring eight inches a day into the Alpine rock face, Sommeiller introduced the first industrial-scale pneumatics for tunnel digging.
		He built a special reservoir, high above the tunnel entrance, to produce a head of water that compressed air (to 6 atm.) for pneumatic drills, able to dig up to 20 times faster.
