OREANDA-NEWS. May 3, 2012. Monitoring the availability of free drinking water at railway platforms along with the passenger amenities at stations is done by Additional General Manager (Zonal level) and Additional Divisional Railway Manager (Division level). Service Improvement Groups at various levels are formed to inspect amenities including drinking water and take remedial measures as needed. Besides, frequent checks are also carried out by officials at different levels. During summer season, when there is a water scarcity and existing sources are found inadequate to meet the water requirements at the stations, water supply is made through tankers.
