The hygiene of toilets in railways presents an ongoing challenge. This paper introduces Clean Tracks, a fully automated sanitization system using ultraviolet sterilization along with hydrogen sulphide (H2S) sensors and smoke/alcohol sensors. Automated flushing and sensor monitoring with proactive maintenance notifications is facilitated in real-time, resulting in more proactive management of toilet hygiene. The findings show that the toilet system was effective in reducing odor, microbial burdens, and increasing user satisfaction and offers a new scalable, smart sanitation option for railways.
