Rail authorities in India are investigating an incident where a freight train was able to travel more than 80 km without a driver. The train was pulling 53 wagons full of chip stones and began rolling downhill along the tracks at Kathua in Jammu, northern India. The train reached a speed of 100 km/h before it could be stopped. The train had reportedly stopped for a crew change in Kathua. The driver and assistant disembarked, and the train began to move. Official sources said that the driver may have forgotten to pull the handbrake before deboarding, though this has not been confirmed by the authorities.
