What implications arise when a train crashes into a buffer stop due to driver fatigue? A recent incident at London Bridge railway station revealed significant safety concerns regarding the management of driver alertness, culminating from a microsleep episode.
On December 13, 2024, at 15:45 GMT, a Southern service collided with the buffer on platform 12 while traveling at 2.3 mph. This occurred despite the emergency brake being applied, as detailed in a report from the Rail Accident Investigation Branch (RAIB). Fortunately, no injuries were reported.
Driver Fatigue and Shift Management
Investigations indicated that the driver’s lack of adequate sleep the previous night was a critical factor, and the shift schedule was designed in a manner that heightened the risk of fatigue. The driver had worked through several rostered rest days leading up to the incident.
In response to these findings, Govia Thameslink Railway (GTR) has implemented what it describes as „robust scientific modeling“ to improve the planning of staff shifts.
Limitations of Safety Systems
The report highlighted that the collision could not be prevented by any of the safety systems installed on the train, as the speed at impact was deemed too low for the systems to activate. Furthermore, it noted deficiencies in GTR’s fatigue risk management capabilities, indicating that the company had not fully adopted certain industry best practices.
Moreover, investigators pointed out that existing safety systems on mainline trains lack the ability to detect brief lapses in driver alertness, which poses a risk not only to drivers but also to passengers and staff.
Recommendations and Future Actions
The Rail Safety and Standards Board has been urged to provide guidance on assessing medical conditions and working hours that may elevate fatigue risk among safety-critical personnel.
In light of the findings, the RAIB has recommended that GTR enhance its fatigue risk management practices by adhering to recognized industry standards. In a statement, Samantha Facey, GTR’s director of safety, health, and security, emphasized the company’s commitment to safety, noting ongoing improvements in fatigue management protocols and increased collaboration with staff representatives.
Facey asserted, „Safety is always our number-one priority and we’re determined to learn from every incident to improve our safety standards for our people and our customers. We’re committed to making sure our staff are fit and alert when they’re at work.“
In August, GTR updated its fatigue risk management standard, which now includes mechanisms for staff to report tiredness. Additionally, enhanced working groups have been established to proactively identify and mitigate fatigue risks.
