Rush hour stampede: At least 22 people were crushed to death last Friday when a stampede broke out in a crowded Mumbai railway station during the morning rush hour. Witnesses said that the disaster was triggered by bits of concrete falling from a covered footbridge that connects two suburban stations – Prabhadevi (formerly Elphinstone) and Parel. Amid fears the bridge was about to collapse, the crowd surged forward; people fell, and were trampled. Officials said the bridge had been more crowded than usual, as people were using the route to shelter from rain. Mumbai’s vast, overcrowded rail network is notorious for accidents. It is estimated that some 3,000 commuters are killed each year; many fall from moving trains, others are electrocuted while crossing tracks, or as a result of slipping onto the line.
