The Railway Ministry, in the last two years, has made six green corridors functional and this was done to demonstrate the advantage of bio-toilets. This is all a part of a plan by the Railways to ensure that bio-toilets are installed in coaches, so that no human waste escapes the train, dirtying the tracks.
Now, the Railways has commissioned 22 sections as green corridors and brought forward its plan of setting up bio-toilets in its entire fleet, by 2019, instead of 2021-22, as decided earlier.
Below are the various sections where this will be implemented.
1) The Daund-Baramati section of 43 km and the Chalisgaon-Dhule section of 56 km in Maharashtra commissioned, under the Central Railway.
2) The Sakari-Biraul 35 km long stretch, in Bihar, commissioned under the East Central Railway.
3) Madhupur-Giridh, a 38 km long section in Jharkhand/West Bengal and the Bhagalpur-Banka 53 km long section in Bihar, commissioned under the Eastern Railway.
4) The Bhojiura-Pilibhit section of 40 km in Uttar Pradesh and Chhapra-Thave of 109 km in Bihar, commissioned under the North Eastern Railway.
5) The Chaparmukh-Silghat 82 km long section, the Katakhal-Bairabi 84 km long section in Assam, and the Arunachal-Vangaichungpao section in Assam/Manipur, commissioned under the Northeast Frontier Railway.
6) The Barmer-Munabao 199 km long section, the Pipar Road-Bilara 41 km long section, the Hanumangarh-Sadalpur 178 km long section, the Anupgarh-Suratgarh 77 km long section in Rajasthan, and the Sikar-Loharu 150 km long section in Rajasthan and Haryana, commissioned under the North Western Railway.
