A relatively new concept of solar water coolers at railway stations has been getting the thumbs up from commuters in Mumbai division. As the water coolers do not use electricity, they are zero-bill and zero-maintenance as compared to their electrical counterparts. They have so far been installed at Mumbai CSMT, Asangaon, Pen, Apta, Roha and this year at Neral and Lonavala stations.

Outside Mumbai Division, they have been installed at Talegaon station in Pune division.
