China’s State Council Work Safety Commission has initiated a comprehensive supervisory investigation into a devastating railway incident that resulted in 11 fatalities and multiple injuries in Yunnan province. The tragic event occurred during early morning hours on November 27, 2025, at Luoyangzhen Station in Kunming, where a specialized test train conducting seismic monitoring operations collided with construction personnel who had entered an active railway section.
The emergency response was immediately activated following the accident, with the Ministry of Emergency Management coordinating search and rescue operations, medical treatment for survivors, and subsequent support measures for affected individuals. The specialized train, identified as number 55537, was performing crucial seismic testing along a curved track segment when the collision occurred.
A multidisciplinary working group comprising representatives from the Work Safety Commission, National Railway Administration, and China State Railway Group has been deployed to the accident site. This team will oversee both emergency response coordination and the detailed investigation into the circumstances leading to the tragedy. Authorities have emphasized the urgency of determining the precise causes and implementing robust preventive measures to avoid similar incidents in the future.
The investigation will particularly focus on safety protocol implementation, track access procedures during maintenance operations, and communication systems between testing crews and construction teams. This high-level response demonstrates China’s commitment to workplace safety standards and transportation infrastructure security.
