A shocking incident occurred at London Bridge station, and it's a wake-up call for the entire rail industry. On December 13, 2024, a passenger train collided with the buffer stop, and the reasons behind this accident are both intriguing and concerning.
The train, operated by Southern Railway, was traveling at a relatively slow speed of 2.3 mph when it struck the buffer stop. Thankfully, there were no injuries reported, but the incident raises questions about driver fatigue and the effectiveness of safety systems.
Here's where it gets controversial: The accident was caused by the driver's failure to apply the brakes in time, almost certainly due to a microsleep episode resulting from fatigue. But what led to this fatigue?
Two key factors were identified: the base duty roster, which increased the risk of fatigue, and the driver's decision to work many of their rest days, further exacerbating the issue. Additionally, the driver had less sleep than usual the night before, potentially impacting their alertness.
And this is the part most people miss: none of the train's engineered protection systems intervened to prevent the collision. The Train Protection and Warning System, designed to automatically apply brakes, didn't engage because the train was below the intervention speed. Other safety systems on board couldn't detect the driver's brief loss of alertness.
So, what went wrong? The investigation revealed that Govia Thameslink Railway, the operator, had not effectively managed fatigue risk, failing to adopt industry best practices. Furthermore, there are currently no safety systems on mainline trains capable of detecting and mitigating short losses in driver alertness.
As part of its investigation, RAIB observed a critical oversight: the actual hours worked by staff were not considered when managing safety-critical personnel with medical conditions.
RAIB has made two recommendations: one to Govia Thameslink Railway to enhance their fatigue management process and adopt industry best practices, and another to the Rail Safety and Standards Board to provide guidance on seeking external advice regarding medical conditions and working hours that may increase fatigue risk for safety-critical staff.
This incident serves as a stark reminder of the importance of fatigue management and the need for robust safety systems. It's a call to action for the industry to reevaluate its practices and ensure the safety of passengers and staff alike.
