The driver of a car train ran over a “stop” in the Vereina tunnel near Klosters GR last summer and collided with an oncoming passenger train. The immediate braking of the passenger train was able to prevent worse, the accident report now shows.
It was thanks to the attentiveness of the passenger train driver that he recognized the risk of a collision in good time, according to the investigation report published on Friday by the Swiss Safety Investigation Board (SUST). No one was injured in the grazing collision between a passenger train and a car train in August 2021.
New system introduced
Just in time for the car train to depart, the signal on the neighboring track had changed from “stop” to “go”. This signal, as well as the signal that the train’s doors were closed, had persuaded the driver of the car train to set off. According to the report, an existing safety instrument had not been used consistently.
The report puts the inattentiveness into perspective in that the engine driver had never seen the signal that applied to him. In addition, the tunnel lighting was not switched on, which made it difficult for the “inexperienced” engine driver to find his way around. The Rhaetian Railway responded to the accident by introducing a new system designed to prevent wrong departures. (SDA)
