The Rail Accident Investigation Branch (RAIB) has released its report into the derailment of a freight train at Maltby North, on a freight only line between Doncaster and Worksop, on 28 June 2006. The full report is available here:

A summary of the key points from the report are: - On Wednesday 28 June 2006 a Freightliner Heavy Haul coal train from Redcar to West Burton derailed on a set of points at Maltby North. Three wagons derailed but they remained upright and did not spill their loads. There were no injuries but 80m of track was damaged.

The immediate cause of the derailment was the points moving position as the train traversed them. One causal factor was the non-implementation of "time of operation locking" for these points, despite it being specified. Although they cannot be proven positively, other causal factors were the likelihood that the driver passed the signal at danger, and that the signaller changed the points just as the train passed over them. There were also three contributory factors.
