More than 150 of Britain's railway stations are request stops. You have to put out your arm to get the train to stop at the platform. In this series, Paul Merton travels around the country by train, only getting off at request stops. Paul hops on and off at a variety of different request stops to tell the story of why they are there, and who uses them. Meeting railways experts and enthusiasts, he explores the history of the stations and learns more about life in and around the stops.
