First put dustbin please then think about segregating. Platform 1 of NDLS does not have a dustbin at least after the food lounge till the Ajmeri Gate road overbridge. For throwing anything you have to go to the food lounge. I was to board the Amritsar Shatabdi and had to go to the lounge to throw wrappers. I saw many people throwing items on the platform itself. The railways is taking swachh tax etc. and I don't think the railways has to invest crores to put some dustbins.
