In order to keep trains clean over 200 of them have been put up against one another to get the top rating as the cleanest in a first of its kind cleanliness survey undertaken by Indian Railways. A similar survey was conducted on stations across the country as part of the Swachch Bharat Abhiyan in 2016.

A total of 475 rakes of these 210 trains are to be audited out of which 386 rakes have already been surveyed.

The survey is being conducted by a third party auditor engaged by IRCTC, an official said.

“Such independent survey on the cleanliness of important trains will be carried out every year and is expected to bring a sense of pride and competition among the zonal railways and maintenance depots. The survey of trains is expected to be completed in a couple of months,” an official said.
