On Monday, in the Chinese city of Chongqing, an unidentified drone collided with a light rail train, often used by passengers for sightseeing. After the collision, the driver had no choice but to slow down and stop the train. Fortunately, none of the passengers sustained injuries, but the appearance of the UAV frightened some passengers. The train eventually continued to move. Law enforcement agencies have already been informed of the incident. An investigation is underway.
