38 derailed train carriages and 800 meters of rails will be removed. Today, the Swedish Accident Investigation Board, the Swedish Transport Administration and LKAB are going to the rugged site to begin the investigation and clean-up of train track tracking on the Ore Line. Already last year, the Swedish Transport Administration alerted for the risk of derailments on the section in question.
The Swedish Accident Investigation Board (SHK) has received a report after Sunday’s derailment, but has not yet made a decision on an investigation.
– What we are doing now is a case assessment, and part of it is to visit the accident site. The decision on whether we will investigate will probably be made within the next week, says investigator Eva-Lotta Högberg.
May soon begin to be revealed
Several criteria determine whether a SHK investigation becomes relevant or not. Among other things, they look at the extent of the damage and for indications of system deficiencies.
– When we have been at the accident site and done our documentation and our investigations, we leave clearance consent. We want to collect the information we need if we are to investigate, it disappears when you start moving vehicles and tracks so we want to do it at once. It can take anywhere from two days to the whole week.
However, the clearing work can to some extent be started before the Accident Investigation Board is fully finished with its assessment.
– Regardless of whether we investigate or not, the actors themselves will investigate the incident, ie those who manage the tracks and have the train company. We cooperate with them and will have contact in the days, if they need to start clearing certain parts, we can give the go-ahead for it so as not to keep the traffic unnecessary, says Högberg.
Risk of derailment in more places
In a report from January last year, the Swedish Transport Administration stated that there is a risk of derailment in several places along the Gällivare – Kiruna train section, reports Ekot. The report was written after one of LKAB’s ore trains derailed in Gäddmyr the same month.
Thirty kilometers of the rails on the section are made of steel of a specific type and year. According to the authority’s investigators, this steel has “an abnormal tendency to develop vertical cracks with a risk of derailment as a result”.
So far, yesterday’s derailment can not be linked to the problem the report highlighted.
