According to China Daily, the preliminary investigation showed that the slippery tracks caused an emergency braking of one of the trains, while the one behind it could not stop in time when going down a slope, so both collided.

The note emphasized that there were no fatalities and that more than 420 people had already been discharged, while 25 were still under observation and 67 were hospitalized for treatment.

The accident occurred the day before during the evening local time, which did not prevent the affected Metro (Changqing) line from operating normally today, except for the sections where investigations are still ongoing.

According to local Transportation authorities, trains will operate in manual driving mode at lower speeds to ensure safety during extreme weather conditions.
