MUMBAI, May 27 -- An early rain test for Mumbai's underground metro stations has not gone well. Aqua Line's Acharya Atre Chowk Metro station, inaugurated only a fortnight ago, flooded in the first heavy rains of the season, on Monday. As a precautionary measure, and to ensure passenger safety, metro services between Worli and Acharya Atre Chowk have been temporarily suspended. Water first began to pour down the steps of the station and into the premises at noon. The water damaged station furniture and even entered the platform areas. Officials said the reason was damage caused to a bund that had been holding water back at an under-construction section of the station. Commuters shuffled through the water until the station was shut soon after flooding just past noon.
