The incident involved train 1H46 (Corby to London St Pancras) and train 1B67 (Nottingham to London St Pancras). The driver of train 1H46, Shaun Burton, sadly passed away and a further 162 people were injured, with a large number requiring hospital treatment.
Early findings suggest train 1B67 came to an unexpected stop after a fault triggered its Automatic Warning System, which applied the brakes.
Train 1H46 then travelled from Bedford onto the fast line and passed a red signal shortly before the collision. Braking was applied only seconds before impact, with the train still travelling at significant speed.
Systems under review
The investigation is focusing on how multiple safety layers interacted, including:
• Signalling and track detection systems
• AWS and onboard protection systems
• Braking performance and response timing
• Driver warnings and situational awareness
• Communications between control, signaller and driver
• Risk controls for train separation at this location
RAIB will also look at the human factors that may have been involved , including workload, fatigue, communication and operational pressures. The emphasis is on how people and systems worked together under real conditions, rather than individual blame.
This is a situation where several safety systems are meant to work together to stop a single issue turning into something more serious. The investigation will look at how those protections worked in practice, and whether anything was missed or didn’t behave as expected.
Findings are still very early, and RAIB has said it is too soon to draw conclusions. The final report will focus on what can be learned and what improvements could help prevent something similar happening again.
