A man prevented a train disaster in India by waving his red underpants in the air. Nimai Das was relieving himself near the tracks at Kopai in the Birbhum district when he noticed that part of the track was missing. Shortly afterwards, he saw an approaching train. He then stripped and began waving his red underpants frantically to stop the train. Luckily, he caught the driver's attention and the train stopped short of the broken line. The authorities say he saved many lives.
