It will take, by the government's own
admission, up to 2021-22 to replace all existing toilets on Indian trains. Railway Minister Suresh Prabhu said one of his priorities was to install 17,000 modern "
bio-toilets", which use bacteria to convert excreta into gases--released into the atmosphere--and treated and chlorinated water. The biggest hygiene hurdle on the Indian Railways are the primitive toilets that discharge waste directly on to tracks, corroding them and stinking up stations and railways corridors. Cleanliness topped Prabhu's
11 priorities, as he announced the
“Swacch Rail Swacch Bharat” (Clean Rail, Clean India) programme. Prabhu said the railways have already
replaced 17,388 existing toilets with bio-toilets over the last three years, spending more than Rs 101 crore. It could cost Rs 3,702 crore ($600 million) to entirely replace the primitive toilets on India's trains, a high-level safety review committee had
estimated in 2012. A total of 12,617 trains
run on Indian tracks every day, carrying more than 23 million passengers in 63,870 coaches (these might also include suburban rail coaches). The Indian Railways has also
allowed 100% foreign investment in installation of bio-toilets. Let us look at the funds spent on installation of bio-toilets:
