Railway report 2015/01
On Thursday 23 January 2014, a tram derailed at a set of points as it was approaching Jar station in Bærum. The derailment occurred at low speed, and no one was injured. The tram line to Jar station had recently started to operate, and the derailment occurred four days after the section was opened. The investigation found that the point blades had not been optimally adjusted, in addition to which the tram had reached its maintenance limit with respect to wear on the wheels.
Safety recommendation
Safety recommendation JB No 2015/01T
On Thursday 23 January 2014, a tram derailed at a set of points at Jar station in Bærum. A contributing factor to the derailment was a sub-optimal fit between the tram wheels and the point blades. This matter had previously been brought to the attention of Sporveien Trikken AS, but the experience had not been sufficiently communicated to the rest of the organisation. In the AIBN's opinion, this was one reason why the risk was not assessed in connection with the Kolsås project.
The Accident Investigation Board Norway recommends that the Norwegian Railway Authority (Statens jernbanetilsyn) request that Sporveien Oslo AS evaluate how knowledge and learning from previous derailments are shared and applied in the organisation, so that they can be used in preventive safety work both in operational tasks and in new projects
