At 07:47 on Monday 9 February 2015, NSB AS’s train 411 collided with the buffer stops in track 23 at Trondheim Central Station. The train entered the station at normal speed and had been instructed to stop on track 23. This is a single-ended siding used when there is too little capacity on the main tracks. When the train passed the points to enter track 23, the driver had started braking without the train having reduced its speed. The driver then engaged the emergency brake, but the speed was still not sufficiently reduced and the train collided with the buffer stops at a speed of approximately 17 km/h.

The weekend before this incident, Trondheim Central Station was hit by storm gusts of up to force 10. Seawater blew in over the station area and left a slippery film on the tracks. The investigation has shown that the Norwegian National Rail Administration does not have an adequate system in place for discovering slippery tracks caused by conditions that can potentially arise in coastal areas.

The investigation also showed that NSB Type 92 does not have an optimal brake system for handling poor adhesion conditions, and that there are weaknesses in the interior securing of equipment on board these trains.

The AIBN submits one safety recommendation following this investigation. The recommendation concerns improvement of the Norwegian National Rail Administration’s instructions regarding measures in connection with unfavourable weather conditions in order to facilitate the identification of risks and the implementation of measures to handle conditions that can potentially arise in coastal areas.

 

The Accident Investigation Board Norway recommends that the Norwegian Railway Authority recommend that the Norwegian National Rail Administration (Jernbaneverket) review its instructions regarding measures in connection with unfavourable weather conditions, so that the risk factors in connection with coastal areas are identified and the necessary measures are implemented.
