During 1963, as the radical reformation of Britain’s railways threatens isolated communities, the New Forest Corkscrew Line falls victim to 'progress’. As he grapples with the closure of Silver Street Station, Porter Sam Smart’s growing conviction that his Station Master is using events to 'line his own pockets’ must be investigated. When the devastating effect on the local community is revealed, Sam enlists the help of teacher Ellen Armitage as he begins to unravel a sixty year old mystery, which may link Silver Street to an antique tin trunk. As shy bachelor Sam fights the impulse to fall in love, he must also discover why he hears the haunting call of a lost steam locomotive, and find out what has the parcel discovered in a hidden Lost Property office got to do with the wartime history of a redundant railway station? A maze of secrets slowly unfold, then the Australian arrives in search of his roots. Now Sam must consider what Alex Ford has to do with Padways Manor and how can he be connected with a train constantly searching for its Last Passenger .
