First transmitted in 1988, the Waterloo to Exmouth train route became very popular after World War Two, with enthusiastic passengers keen to embark on self-planned expeditions in the more rural climes of Exmouth. Railway enthusiast Barry Smith was one such passenger who travelled along this route on the 'ACE', the Atlantic Coast Express, during his childhood. In this episode, Barry retakes the journey in the hope of rekindling his boyhood enthusiasm for this once popular railway route. En route Barry comments on the dramatic changes that have taken place since the age of steam.
