Indian Railways is reportedly planning to use the Internet of Things (IoT), new chemicals and standardised watering systems to solve the problem of dirty and unhygienic train toilets. Various proposals include using Viliso Technologies for odour monitoring, introducing hot water showers in BEML-make sleeper VB trains and examining Clonon concentrate for cleaning. For this technology, a Mumbai-based startup, Viliso Technologies, which specialises in odour monitoring, has been shortlisted. To study the efficacy of the technology, it will be used in some coaches of the Linke Hofmann Busch and Integral Coach Factory variants.First driverless train in August in ChennaiMetro rail commuters can soon travel in a train with an operator’s view as the first driverless trainset may arrive in August.
