Eight students in Mumbai have developed a vacuum cleaning system for train coaches, according to an article on the Cleanzine website. The students — five of whom are US citizens and all aged 12-14 — visited Vadodara and Mumbai stations to study the trash disposal in train coaches before creating the system.

The system is designed to provide for split vents in each compartment of the coach, operated by a foot pedal, which enables passengers to deposit their trash. The trash is then sucked into a vacuum system, which pulls it to a chamber under the coach.

The students, from Juhu and Andheri, working as part of the robotics club, recently demonstrated their work to rail officials who consider it a “feasible” option for the future.
