Paul Merton's Secret Stations

Paul's journey begins in the Highlands, travelling on the stunning Kyle Line to the request stop of Attadale, where he meets Joanna and Alec Macpherson, who've recently moved from Peckham to look after a vast 30,000-acre estate at the shore of Lochcarron. Paul's next two request stops are on the Cumbrian Coast Line.

Paul Merton continues his journey around Britain's railway request stops on the glorious West Highland Line and Beasdale, where the Special Operations Executive taught espionage in World War Two. Paul discovers a request stop just outside the centre of Bristol. And at Pontarddulais, Paul sees how a former mining town has reinvented itself as 'the wedding village' - with a high street full of bridal shops. Paul helps a young bride pick out her perfect dress, and has the chance to sing with the local male voice choir - the most successful choir in Wales.

This concluding episode begins on the stunning Pembrokeshire coast. From the request stop of Penally, Paul visits the trenches built for training during World War I. At Luxulyan in Cornwall, Paul looks for the hidden remains of local china clay mines. In Greater Manchester, Paul visits Reddish South - a request stop famous for having only one train a week. And for his final stop of the series, Paul goes to Corrour on the glorious West Highland Line, with a stop that's ten miles to the nearest public road.
