Indian people crowd a door of a train as they wait for the train services to resume following a power outage at a railway station in New Delhi, 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 blackout. Hundreds of trains stalled across the country and traffic lights went out, causing widespread traffic jams in New Delhi. (AP Photo/Kevin Frayer)
