Exactly twelve months after the incident that wrecked infrastructure at Petteril Bridge Junction, Carlisle, in northwest England, the national inspectorate has released its final report. The Rail Accident Investigation Branch (RAIB) has unveiled its findings following a comprehensive investigation into the derailment in autumn last year. The spectacular accident caused no injuries but saw track, signalling, and a vital bridge all badly damaged and sent freight wagons crashing into a river on the edge of the important railway town of Carlisle back on 19 October 2022.
