Swedish Accident Investigation Criticizes Trafikverket Over Rail Failures

The Swedish Accident Investigation Authority (SHK) has concluded that Trafikverket failed to maintain necessary safety levels following severe weather in Västernorrland in September 2025. Heavy rainfall caused extensive flooding and damage to roads and railways, resulting in a fatal road accident and two train derailments.

The derailments caused significant disruption to rail traffic between northern and southern Sweden, affecting the Stambanan genom Övre Norrland, Botniabanan, and Ådalsbanan. While some services resumed in mid-September and early October, the investigation highlighted systemic failures in weather preparedness.

Investigator Alexander Hurtig stated that although Trafikverket had access to rainfall data, the established processes for operational weather preparedness were used only to a limited extent and lacked structure. The authority noted that weather forecasts and reports of flooding were not integrated into a documented risk assessment, and operational managers failed to implement necessary traffic restrictions.
