After ranking 407 major stations on cleanliness, Indian Railways has undertaken an elaborate, independent audit-cum-survey exercise of 200 important trains, including the Shatabdi, Rajdhani, and Duronto. The cleanliness of toilets, quality of linen, performance of the onboard housekeeping service and the types of chemicals used for cleaning are some of the items on the checklist of the audit teams. Though stations have been audited twice in the past, this is for the first time that trains are being examined by audit teams for cleanliness.

Apart from 72 pairs of premier trains, services of 128 trains, including the Jan Shatabdi, Sampark Kranti, Intercity and other distant mail/express trains, will be covered by 50 audit teams formed to do the job in the next couple of months. The audit teams have spread out in all zones to collect feedback from at least 100 passengers of each premier train and 60 passengers for each mail/express service.
