The railways has about 8,000 stations which are classified into seven categories - A1, A, B, C, D, E and F - based on their annual passenger revenue.

The stations which contribute more than Rs 50 crore a year in passenger revenue are considered to be A-1 stations. The A category stations contribute between Rs 6 crore and Rs 50 crore as annual passenger revenue.

All suburban stations are in C category, while all halts are in F category. The railways will now carry out a survey of 200 trains on cleanliness.
