London’s Secret Cold War History
BT Openreach engineers have been busy recovering redundant Cold War era cable from an underground tunnel network in London recently. Teaming up with a specialist mining company, BT hired a small 1.75 tonne Clayton locomotive to help reclaim the heavy copper cables from deep within the six-and-a-half mile tunnels and transport them to the surface.
The tunnel network was originally built by the Post Office in 1911 to transport up to four million letters and parcels a day under the streets of London and was also used in later years to help protect the UK’s defences.
