evidence: India’s extensive railway network is the lifeline of the nation, ferrying millions of passengers and tons of cargo daily. Ensuring cleanliness and hygiene on trains is a top priority. To address this concern and contribute to environmental sustainability, Indian Railways has embarked on a remarkable journey by introducing bio-toilets. These innovative waste disposal systems are transforming the railway experience, enhancing hygiene, and promoting a greener future. In this blog, we explore the world of bio-toilets in Indian Railways, backed by official data sources. [...] Before the introduction of bio-toilets, Indian Railways faced a significant challenge: the discharge of human waste directly onto the tracks. This not only posed environmental and sanitation issues but also jeopardized the safety of track workers. Traditional toilets on trains relied on a system that allowed waste to fall onto the tracks, resulting in unsightly and unhygienic conditions. [...] Official data from the Ministry of Railways reveals the scale of this green transformation. By the end of 2020, Indian Railways had installed over 2.4 lakh bio toilets in coaches across the network. This massive rollout demonstrates the railway’s commitment to improving hygiene and reducing environmental impact.
