This was the moment 45 years ago when workers deep under the streets of Newcastle marked a major milestone in the completion of the Tyne and Wear Metro.
The Chronicle reported on February 25, 1977: "Tunneller John Thorkildson pushes his way through the last few yards of earth to complete the link-up of the Metro's main tunnels near Grey's Monument.
"The tunnels met under Grainger Street a few yards south of the monument which will become the site of one of the system's major stations."
