Power services slowly restored in Mumbai after a sudden outage brought the commercial capital of India to a grinding halt. Train services, too, were hit as pictures of passengers waiting in a queue on railway platforms started circulating on social media. Pictures of people walking on railway tracks to reach their destination were also shared.
