evidence: New Delhi: On the World Toilet Day on November 19, Central Railway (CR) department announced that it will be introducing e-toilets in the railway coaches for the first time as a special initiative. This first-of-its-kind concept is being undertaken on a pilot basis in coach (3A), part of Train no. 11013 Lokmanya Tilak Terminus–Coimbatore Express (LTT Coimbatore) for performance and customer feedback. If successful, these toilets would be installed in other coaches as well. [...] Railway Minister Piyush Goyal, earlier this year, took to Twitter to inform that Indian Railways has installed highest ever bio-toilets in train coaches in 2017-18, which is 64 percent higher than last year, taking the total number of bio-toilets in coaches to 1.25 lakh. [...] The bio-toilets however, have been prone to clogging due to dumping of waste such as bottles, pouches, plastic cups, paper and other material in the pans — resulting in foul smell. Hence, Mr. Goyal announced that the railways are mulling to replace all the 2.5 lakh toilets inside train coaches with vacuum bio-toilets.
