* Work on the extension to Corwen will be featured on the BBC programme.
A programme featuring Llangollen Railway and the Dee Valley, which was recorded in late March, is due to be broadcast on BBC Radio Wales this Sunday at 7am.
The visit featured a ride down the line in the heritage railcar and a trip out to Corwen to see the extension works.
There were interviews with various people extolling the scenic delights of the Area of Natural Beauty in the valley.
The BBC website includes a gallery of photos taken during the visit when the production team rode the Wickham railcar and visited the Corwen extension.
