A look into the preserved 6 car DEMU 1001 which ran on the Hastings line from London. The DVD goes into St Leonard's Depot, home to Hastings Diesels Limited who have preserved the unit and now operate it. It then reviews some of the railtours operated by the unit in preservation, including its 2008 visit to Folkestone Harbour. A bonus inclusion is a feature on fellow Thumper, 1101, at the East Kent Railway.
