Large parts of Mumbai and its suburbs are facing a power failure, due to which several trains have been held up. The outage, according to the city's electricity supply board, is because of the "TATAs incoming electric supply failure". Traffic signals at some areas too have stopped working. Mumbai airport and the stock exchange are functional.
Western Railway said the breakdown is due to a grid failure at Tata Power. Commuters were seen walking on rail tracks. Such a large-scale power failure is unprecedented for the country's financial capital.
