This study set out to investigate the types of train driving tasks and situational factors that might lead to low workload and reduced driver performance. It also investigated the effect that a mitigation designed to increase workload had on train drivers experiencing a relatively undemanding train driving scenario. The mitigation chosen was a series of task-related questions that were administered verbally by the experimenter, at fixed time intervals. Ten participants were recruited to take part in the study. Participants were required to complete two drives on Southern Railway’s train simulator: one baseline drive and one in which the mitigation was applied. Subjective and physiological measures were taken for both the baseline and mitigation drives, as well as performance measures such as speed and response to critical events. The results from the study seem to suggest that applying a mitigation technique increases workload during a monotonous train driving scenario and has a positive impact on subjective measures of low workload, low arousal and fatigue.
