It’s a great surprise to notice that none of the Chennai Metro Rail stations have toilets. The design plan of none of the 31 stations shows toilets for passengers and officials confirm this. According to metro rail officials, the exclusion of toilets from the design is due to the fact that even Delhi metro and several metros abroad do not have toilets: the idea is not to have passengers inside the station for long hours.
Three of the metro stations, including Koyambedu, Vadapalani and Ashok Nagar, have been identified for giving out commercial space which will have shops and offices. Tenders for these have been floated. But even for these spaces, there is no provision for toilets, mandatory or otherwise.
