Digging under the Chiltern Hills has started today for the HS2 rail route.
A 10 mile tunnel will be dug under the Chilterns, in a bid to reduce the impact of the high speed trains going through the countryside, and instead will go underneath it.
The 2,000 ton machine, named Nightingale after local figure Florence Nightingale, will work non stop for 3 years.
It is the next step in the Phase 1 part of the construction, connecting London with the West Midlands.
