A speeding train derailed in western India early on Saturday - killing at least nine people and injuring more than 80 others. Sources say fifteen coaches of the New Delhi-bound train flew off its tracks when the driver suddenly applied the brakes because of poor visibility in the region. The accident occurred near Banshkov, a village around 25 miles south of Jaipur, the capital of Rajasthan state. A broken rail track pierced an air-conditioned coach and killed some of the passengers. Rescuers used equipment to cut open some of the coaches to free those trapped. The injured were taken to Jaipur SMS Hospital. Accidents are common on India's sprawling rail network, one of the world's largest - with most blamed on poor maintenance. Last month, a passenger train crashed into another train's rear carriage in northern India, killing 22 people and injuring 16 near Agra, the home of the Taj Mahal.
