After being evicted from the family car-repair business, the Carters get involved in the re-opening and running of the Flockton to Lane End railway, an old branch line that’s been disused for years. The star of the show is a vintage ex-Great Western locomotive called, for the series, "The Flockton Flyer". After the eviction, the Carters set up home in Flockton Station, meeting up with a tramp by the name of Bill Jelly, who's been living in a track-side hut. Before being allowed to move in to the station, Bob Carter makes an agreement with Commander Frost (Chairman of the railway re-opening society) that he'll get the engine and the track ready for re-opening. Some of the locals are not happy about the re-opening plans leading to a falling-out with farmer Joe Pratt, as well as vandalism to be dealt with. One adventure involves a train robbery, where "The Flyer" is used to trap the crooks until the local police can be summoned. In the final episode of series 1, all's ready for the opening day, complete with band, bunting and cakes, but "The Flyer" goes missing!
