Indian Railways has started implementing an artificial intelligence (AI)-based monitoring system to tackle the problem of unhygienic conditions. According to details revealed by Chief Project Engineer Laxman Jain, this pilot project has been implemented in 100 trains across the country. The system works through a mobile application, where staff have to register attendance and upload photos before and after cleaning the toilet. AI will analyse these photos and assess whether the cleaning has been done as per the quality standards.
