I've never seen anything like the vacuum cleaner rail engine before. A re-purposed old railway train, it rides along the tracks and picks up garbage along the way with an elephant-like trunk.
Based in India, the Vacuum Cleaner Rail Engine was made in the Parel workshop by Central Railway engineers. An extremely green project, it not only is a recycled concept, but it is also a piece which travels around cleaning up the planet. This massive garbage collector is definitely unique, but most importantly, it is helpful to the environment.
