A team visited the Rhondda Tunnel today. The visit was principally for Hammonds ECS to measure the dimensions of the air shaft concrete cap from below so that they can replace it with a hatch. Mines Rescue of Dinas provided safety cover and escorted the teams through the tunnel. In the team was a tunnelling expert from Balfour Beatty; Balfour Beatty is going to carry our a detailed examination early next year. They were accompanied by members of the RTS Technical Subcommittee and our Vice-Chair. Also accompanying us was the editor of the Forgotten Relics website who took some amazing pictures of the tunnel. It is a remarkable structure, especially as it has not had any maintenance for almost 50 years and has hardly changed in all that time. Notice that the Blaengwynfi air shaft cap has a recent wound in it. The middle bottom picture is the water running into the drain. We are not sure where that water goes but it does not stay in the tunnel. Watch this space for more pictures soon.
