Eleven railway workers were killed and two others injured when a train struck a maintenance crew on the tracks near Kunming, the capital of China’s southwestern Yunnan province, on Thursday. The workers were reportedly testing seismic equipment used for earthquake monitoring when the train approached unexpectedly. Authorities said the train was traveling at normal speed as it entered Laowang Town Station. The Kunming Railway Bureau has launched an investigation to determine how the accident occurred. Officials described it as China’s deadliest rail accident in more than a decade. Train services at the station have since resumed. China’s vast rail network, one of the largest in the world, carries billions of passengers annually but has occasionally seen major accidents, including a 2011 collision in Zhejiang that killed 40 people and a 2021 incident in Gansu that left nine workers dead.
