However, the driver’s daughter (Pauline Johnson) discovers the plot and boards the train to warn her father and his new assistant (a debuting Ray Milland), who had trysted with her the night before.
The story concerns a stoker’s (Alec Hurley) attempts to sabotage a driver’s (Moore Marriott) last London-Edinburgh run before his retirement after the latter had reported him for drinking on duty. However, the driver’s daughter (Pauline Johnson) discovers the plot and boards the train to warn her father and his new assistant (a debuting Ray Milland), who had trysted with her the night before. Filmed on the Hertford loop line, the action is most notable for low-angle views of the speeding locomotive, the footplate close-ups and the daredevil shots of Johnson performing her own stunts in edging along the narrow running board in heels.
