Overview
- Valais police reported 29 people on board, with five injured, one taken to hospital in Sion and the rest evacuated safely.
- The derailment occurred around 7:00 a.m. near the Stockgraben/Stockgalerie area as the train exited a tunnel, and officials say it remains unclear whether the slide struck the train directly or crossed the tracks moments before.
- Swiss Federal Railways suspended traffic on the Frutigen–Brig line between Goppenstein and Brig, with operations still halted as authorities assess conditions.
- The Valais public prosecutor opened an investigation into the circumstances of the accident, which police linked to avalanche activity.
- Avalanche danger was at level 4 at the time of the crash, and Swiss monitors raised parts of the southwest to the maximum level 5 on Tuesday, prompting evacuations in Orsières.
