Operational Safety Indicators Using Real Train Driving Data

This paper explores the utilization of On Train Data Recorders (OTDR) in monitoring train safety systems use. Train Protection and Warning System (TPWS), Emergency Bypass Switch (EBS) and the Driver's Reminder Appliance (DRA) were used as examples of train safety systems. Using OTDR data to monitor safety systems has to potential to improve compliance with the Rule Book, especially if data can be collected and analysed in real-time. Identification of the deviation from recommended rules that may have safety implications may be useful in the pre-incident investigation.
