Train operator workload incorporated with station duties for passenger service at dwell time was evaluated based on the Critical Flicker Fusion Frequency (CFF) and the Heart Rate (HR) measured during duty time. Test results proved the followings. CFF was lower than the standard level while operators were on duty or after they were released, and higher immediately after an off-duty time. The mental workload evaluated by increases in HR remained unchanged irrespective of additional duties.
