The Office of Work Safety Commission under the State Council has launched a high-level inquiry into a train accident that killed 11 people and injured two others in Kunming, Yunnan province, according to the Ministry of Emergency Management on Friday.

The incident occurred in the early hours of Thursday at Luoyang town railway station, where a test train travelling through a curved section of track struck a group of construction workers who had entered the active line.
