10,000 Bio-toilets installed in 2,700 Rail Coaches in 2015-16
“Bio-toilets are being fitted in new coaches. Existing in-service old coached are also being retrofitted with bio-toilets in a phased manner. However, there is no fixed target for 2016-17,” the Railways said.
“It is planned to eliminate direct discharge from toilets in all coaches by 2021-22, provided there is no setback to development and deployment process,” said the Railways.
