Indian stranded passengers wait on a platform and some of them on rail tracks for the train services to resume following a power outage at Sealdah station in Kolkata, India, Tuesday, July 31, 2012. India's energy crisis cascaded over half the country Tuesday when three of its regional grids collapsed, leaving 620 million people without government-supplied electricity for several hours in, by far, the world's biggest-ever blackout. Hundreds of trains stalled across the country and traffic lights went out, causing widespread traffic jams in New Delhi. (AP Photo/Bikas Das) less
