i guess its the passengers who are responsible. we dont respect our own country, we do not have pride in defiling our national carrier, we as a nation have been poor about such trivial habits, spit , defecate, defile, draw graffiti, stick posters, pass urine, puke at any corner, pick nose, dirty the compartments, drop trash all over the country side. phew! i guess its the passengers to blame. the railways are expected only to ensure there's enough water, enough trains to handle the humongous load, peroper governance and strict fines for defiling a public means of travel.
