Durantos don't have ANY commercial halts, only technical halts for change of running staff... there is no question of beggars, etc. you mention, IN the whole train. And this is escorted train.. Good wishes. You can get off at the technical halts, which you don't know when it will be, and because of that and other restrictions, you can't book from the technical stations, and therefore the question of other passengers getting in from stations other than the From station does not arise. If they do, they will be detrained at the next halt, whether it is a station or not... which means any danger where train comes to a halt on the track ! Good wishes.
