-5165 Occurrence Summary What Location Date of occurrence 09-09-16 Location name O Porriño (Pontevedra) Local time 09:25 Latitude Event type Railway vehicle movement events Train derailment Longitude Description Passenger train derailment and collision, at the entrance of Porriño station Direct Cause descrip The derailment was caused by an excess of speed of the train when passing the diverted switch at the entrance of Porriño station. Previous signals had ordered the train to slow down, but the driver didn t comply with those orders, although he confirmed reception. Evidence and tests have ruled out any failure in signals, brakes or visibility, so most likely cause was a human error in signals interpretation. However, this is not concluding, because of the lack of recordings in cabin and direct witnesses (driver himself and train guard were among the fatalities). Some hints point to a possible distraction (previous incompliance of a speed limit, possible presence of the train guard in the cabin).

Previous signals had ordered the train to slow down, but the driver didn t comply with those orders, although he confirmed reception. Evidence and tests have ruled out any failure in signals, brakes or visibility, so most likely cause was a human error in signals interpretation. However, this is not concluding, because of the lack of recordings in cabin and direct witnesses (driver himself and train guard were among the fatalities). Some hints point to a possible distraction (previous incompliance of a speed limit, possible presence of the train guard in the cabin). Underlying and root causes description Routine habits and low frequency of travelling could have influenced the driver s behaviour. The driver only drove this section once every 3-4 weeks, in a different country with different rules and signals. Moreover, those times he drove, situation was always the same: 25 km with no stops nor diversions, with several speed restrictions that didn t apply to this train ( simply go ahead ). This, combined with the low frequency of travelling, could have led to a poor consolidation of knowledge about line, a wrong risk perception and a possible habit-based driving, prone to a lower level of attention to signals. Moreover, signals beacons that warned to slow down were positioned amidst other beacons with trivial messages (speed restrictions that didn t apply to this train), so (in the described situation of lower level of attention) they could have been confused with those trivial warnings (although this beacons arrangement was not against rules, it has been modified). This combination of factors (possible habit-based driving + possible distraction + sub-optimal beacons arrangement) could have caused the wrong response to the instructions of the signals. On other matters, the train was diverted by the IM for checking a track circuit, according to a usual practice. However, this procedure is not properly defined in the SMS and it has traceability issues. Risk management in this situations has to be solved.
