Indian commuters exit an underground metro station where services are fully restored after Tuesday's power outage in New Delhi, India, Wednesday, Aug. 1, 2012. Factories and workshops across India were up and running again Wednesday, a day after a major system collapse led to a second day of power outages and the worst blackout in history. An estimated 620 million people were left without electricity after India’s northern, eastern and northeastern grids cascaded into failure Tuesday afternoon. (AP Photo/Rajesh Kumar Singh) less
