Ffos-y-Fran in the Welsh town of Merthyr Tydfil has been extracting coal for more than 15 years, but it isn’t supposed to be operating now.

Its permission to mine ran out last September. So, ClimateCast host Tom Heap and the team travelled there to find out why it’s still in action, what’s happening to the coal, and when operations will stop.

On this episode Tom speaks to Chris and Alyson Austin, who live near the coal mine, steam train enthusiast Steve Oates, who is chief executive of the Heritage Railway Association, and Delyth Jewell, a Plaid Cymru Senedd member for South Wales East and the party’s climate spokesperson.
