Network of ‘creepy’ underground tunnels abandoned after dynamite tragedy over 100 YEARS ago transformed and reopened A NETWORK of abandoned underground tunnels have been transformed and reopened to the public.
Those tunnels were blasted through the rock by dynamite - a dangerous job with two deaths linked to the construction of the line.
The Tregarth Railway Tunnels in Wales were once part of a passenger railway line.
But it required two viaducts and two tunnels to navigate rivers and hillsides.
Roland Evans, 35, died after being consumed by a fall of rock and brickwork after a period of heavy rain while working on the line on March 12, 1885.
