The stations of Indian Railways have been classified into 7 categories viz., A-1, A, B, C, D, E & F. Deluxe Toilets should be provided in the circulating areas of A-1, A & B category of stations with value added services. Normal Pay & Use toilets should be available at platforms of A-1, A and B category stations at one end.
