Each section of the tunnel weighs 30,000 tonnes – over six times the weight of the Royal Navy frigate HMS Chatham.
The tunnel needed 100,000 cubic metres of concrete weighing 250,000 tonnes and requiring 20,000 truck loads to deliver.
The 1,500 miles of steel bars used to reinforce the concrete, if laid end to end, would stretch from Chatham to Moscow.
