Grayrigg derailment [SEP] Cause
Experts compared the cause to that of the Potters Bar rail crash in 2002. On 26 February, an interim report published by the Rail Accident Investigation Branch outlined the current progress of the investigation. The report contained a single conclusion, that the immediate cause of the accident was the condition of the stretcher bar arrangement at points 2B at Lambrigg crossover, which resulted in the loss of gauge separation of the point switch blades. The stretcher bars (components that hold the moving blades of the points the correct distance apart) had been found to be disconnected or missing. Of the three bars, one was not in position, another had nuts and bolts missing, and two were fractured.
