C37/1997R Freight wagon derailing at Lauritsala, on November 7, 1997

On Friday, November 7, 1997, a Russian freight wagon as the last wagon in a freight train, derailed at Lauritsala. When the derailing took place the train was moving over to a secondary track. As a result of the derailed wagon and the damaged track, rail services had to be interrupted on the track for five hours. The financial loss generated by the accident amounted to a little less than FIM 20 000.

The derailment was caused by a blocking of a worn bogie pivot of the trailing bogie of the Russian wagon. The bogie refused to turn as controlled by the turnout blade and continued straight ahead, and then the wheel flange rose over the turnout blade.

In order to prevent similar accidents, the Accident Investigation Board of Finland repeats its earlier recommendation (C4/96R/S58) on an ascertainment of the condition of the bogie pivots in Russian wagons.
