C3/2004R Wheelset of freight train locomotive derailing at Koskenkorva station on 30 March, 2003
On Sunday March 30, 2003, at 17.15 hrs, the rear wheelset of the locomotive of a freight train derailed at Koskenkorva station when the train ran into a log of birch wood lying lengthwise between the tracks. As a result of the incident, the Dv12 dieselhydraulic locomotive in question, two wooden decks of level-crossing, and track and safety installations and track equipment over about 170 meters were damaged. No personal injury was generated by the incident. The resulting total costs amounted to about € 7,900.
The direct cause of the incident was the locomotive bumping into the birch-wood log lying between the tracks. As a factor contributing to the generation of the incident, the engine driver failed to brake though he perceived the log well before the bumping into it. He did not even brake when the log hit the locomotive.
In order to prevent corresponding incidents in the future, the Accident Investigation Board of Finland recommends that the person responsible for the checking of the travel condition of the train, pay more attention to an appropriate loading of the train and whenever necessary, tie the load, before giving the train a departure permission.
