NEW DELHI: Six railway stations in Rajasthan, including three from the capital region of Jaipur, bagged the top 10 places in a railway cleanliness survey which was released on Wednesday. The three stations that fall in the state capital are Jaipur (ranked no.1), Durgapura and Gandhinagar. The other three are Jodhpur (2), Udaipur (8) and Ajmer (9).Among 109 suburban stations, Andheri station in Mumbai, and Virar and Naigaon stations on its outskirts were found to be the cleanest, according to the report released by railway minister Piyush Goyal . The other stations that found place in the top 10 were Jammu Tawi, Suratgarh , Vijaywada and Haridwar .A total of 720 stations were ranked based on different parameters, and the process also involved taking feedback from passengers and direct observation by third-party assessors. Suburban stations were included for the first time in this survey and even green cover at stations was considered while ranking them. The report named North Western Railway as the cleanest railway zone, followed by South East Central Railway and East Central Railway.Releasing the report, Goyal said cleanliness at stations and in trains has improved dramatically in the past five years while claiming that there has been a significant transformation from “suffer” to “safar”. Railway board chairman VK Yadav said the overall score of all stations had gone up in recent years and it was a sign of better cleanliness across all stations.Rajesh Agrawal, member (rolling stock), railway board, said the installation of bio-toilets in trains has addressed the problem of about 50 lakh tonnes of human waste falling on railway tracks every day, causing corrosion and resulting in a cumulative loss of Rs 500 crore a year. He added that the use of water to clean coaches has also reduced from 15,000 litres per coach to barely 300 litres by putting automatic washing plants. In the past one year, about 100 such plants have been built across the country.Interestingly, the survey also flagged the need to take up more water conservation measures at stations. It found that only 182 stations (25%) had this provision while barely 62 stations (9%) had provisions for using waste water.
