Atleast in Chennai central, Mumbai CST and i am sure many other big stations which are terminuses, luggage can be moved from one platfrom to another with trolleys. So slowly phasing out coolies without making the present porters unemployed, can be tried in these big stations. When i said user friendly trolleys, i meant easily movable without strain on the passengers. And for those talking about scams on trolley purchases, if we are not capable of punishing the scamsters fast, we should not think about improving quality of life and remain in dark ages while the other parts mof the world is fast developing.
