A group of college-bound seniors at Baruch College Campus High School will soon be heading to MIT to present a detachable rubbish vacuum that they designed and built for use in the subways.

What they came up with is an alternative that they hope the MTA will use to keep the subway tracks clear. The agency currently has entire work trains dedicated to vacuuming up garbage on the tracks, but the prototype that the students have created would instead attach onto the MTA’s existing work trains and, they say, would require less maintenance.

To create the prototype that they primarily worked on in the cramped back section of a classroom, they used motors and filters from actual vacuums, but added on features to make it semi-automatic. The device, which was built on a smaller scale than the real thing to cut down on expenses, has light sensors on the top so it kicks on when it pulls into the station and turns off when back inside the tunnel to conserve energy. Their version operated while plugged into the wall, but in practice the vacuum would draw energy from the third rail, which would also make it more powerful.
