This episode follows an international team of engineers and construction workers as they attempt to build a brand new epic metro line underneath the Danish capital of Copenhagen. Called “Cityringen”, this ambitious project is the largest feat of engineering the city has seen for over four hundred years.
The programme follows the tunnelling project manager, Valerio Violo and his team as they race to tunnel between 17 brand new stations using four giant tunnel boring machines. They will excavate over nineteen miles of new train tunnels, lay 22 miles of track, dig through toxic earth and navigate their way under the capitals the busiest railway station – whilst it remains open!
Across town another team is busy finalising and testing the 39 new driverless trains that will run on the new line. Costing over £2.5 billion this giant Cityringen project will bring 90% of the city’s population within a 10-minute walk to a station and will help alleviate congestion on the roads.
But building a project of this magnitude isn’t without its challenges; as we follow the team they face a flooding station as a giant tunnelling machine is about to break through into a new platform and fears are realised as work underneath the city’s busiest active railway station causes alarms to trigger.
