This extraordinary time-lapse footage shows a near four-month effort to prepare the set for Europe’s biggest ever disaster training drill.

Parts of Littlebrook Power Station near the Darford Crossing have been transformed into the wreckage of a building after its collapse on to a Tube station.
The short clip shows cranes being used to manoeuvre seven crashed Tube carriages and diggers depositing rubble amid the debris.
The “Exercise Unified Response”, involving a range of London’s emergency agencies, has been more than a year in the planning, the London Fire Brigade said.
London Fire Commissioner Ron Dobson said: "Exercises of this scale are important to ensure that we are always ready to respond no matter what happens.
