Indian Railways — sleeper coaches in day train

Address:

Chennai, Tamil Nadu

cholan express is a day train. starts chennai 8.15 a.m reaches tiruchy 16.35 p.m. and on return journey starts tiruchy 9.35 a.m reaches chennai 17.50 p.m. so it is a hundred percent day time train. but originally it was running up to kumbakonam etc and there was sleeper coaches attached to it. but it runs up to tiruchy now. but the sleeper coaches are there and extra cost is plucked out from the passengers. railway may think that Indians are always sleepy and they will sleep even during day time. but we are blabbering on other side that we are going to become super power country soon. if rules are there that for changing coaches etc railway will have to get permission from ministry like that change that rules it self. don't say that we have to get permission from world health organisation W.H.O and World Bank and United Nations Organisation U.N.O.
