The Rail Accident Investigation Branch is probing the Sept. 6 derailment of a freight train traveling between Peak Forest and Salford.
The train derailed around 11:25 a.m. on Sept. 6 as it passed over a bridge in Audenshaw, Manchester.
The train involved comprised two class 66 locomotives and 24 wagons, which were loaded with aggregate. The 2 locomotives and the leading 10 wagons passed safely over the bridge.
The next nine wagons derailed, with the last coming to a stand on the bridge itself.
No one was injured in the derailment. However, it caused substantial damage to railway infrastructure and damaged some of the wagons involved.
The investigation seeks to identify what led to the mishap. It will also consider the condition of the infrastructure, the status and condition of the wagons involved and any underlying management factors.
The RAIB will publish its findings, including any recommendations to improve safety after its investigation concludes.
