- [Salisbury train crash 2021: what the RAIB report found](https://afterthereport.usamakhaliq.com/salisbury-train-crash-2021-raib-report/): Two passenger trains collided at Salisbury Tunnel Junction on 31 October 2021. The RAIB's 113-page report traces it to leaf contamination and drizzle after a scheduled railhead treatment was postponed, a late braking point, and train brakes that could not cope, with Network Rail's autumn arrangements underneath. Five of its ten recommendations are now closed.
- [Leaves on the line: low adhesion in rail accident reports](https://afterthereport.usamakhaliq.com/low-adhesion-leaves-on-the-line/): Why can a train not stop on leaves? What UK accident investigators have found about low adhesion, the defences meant to cope with it, and where those defences fell short at Salisbury in 2021 and Talerddig in 2024.
- [Talerddig train collision: what the RAIB report found](https://afterthereport.usamakhaliq.com/talerddig-train-collision-raib-report/): Two trains collided head-on on the Cambrian line in October 2024. The RAIB's 139-page report traces the crash to low adhesion, a sander fault that routine testing could not detect, an unused emergency sander, and a signalling scheme that relied on working sanders.
