Preliminary investigation shows the separation of carriages accident along the Changping Line of Beijing subway on Thursday evening was due to the snowy weather, which affected the train's braking system, resulting in a rear-end collision with the front train, Beijing transportation authorities said on Friday.

Around 11:00 pm on Thursday, the personnel transfer was completed, and the on-site disposal work basically finished. A total of 515 people were sent to the hospital for examination, and 102 people were found to have suffered fractures, with no fatalities, the authorities said on Friday. 

According to the authorities' announcement, the accident occurred as a result of the slippery tracks caused by the snowy weather. The preceding train had to make an emergency brake to stop. Unfortunately, the following train was situated in a downhill section, making it difficult to effectively brake due to the snowy conditions.

Beijing transportation authority apologized for the inconvenience, fright, and injuries caused to the passengers in this accident, and vowed to do a good job in carrying out post-accident work and conduct a comprehensive investigation to improve extreme weather operation and emergency response to ensure the safety of operations.

It was at 6:57 pm on Thursday, when a rear-end collision occurred in the section between Xi’erqi to Life Science Park stations of the Changping Line. The municipal government officials immediately went to the scene and set up a working group for on-site accident disposal. The relevant departments including transportation, firefighting, health, public security and emergency response responded quickly and made efforts for rescue, according to the authorities.

As of 6 am on Friday, 423 people have been discharged from hospital, 25 people are under observation, and 67 people are receiving hospital treatment, the authorities said.

On Friday, Beijing Subway apologized again over the incident, while putting in place measures to reduce inconvenience for passengers.

Currently, the Beijing municipal government has established an investigation team for the Changping Line accident, which will further investigate the cause of the accident, evaluate the emergency response, and learn lessons from the accident, effectively carrying out rectification measures.
