1. % Quota allocation isnt fixed & differ for different trains, even in same route!! Its moving ratios & gets changed time to time (demand scenario, festive rush etc) & hence nothing in stable print format!!
2. There isnt any concept of "WE" in IR but Railfan do keep check on AVL Status of particular trains & if the AVL berth pertains to some shocking stats (as like 60-65% AVL), they treat it WE, while real picture may differ for some trains!!
3. U should refer TTE & if failed then RPF!! They...
more... simply will act under these circumstance!!
4. If its AC Coach, then Attendant & in case its SL, then inform TTE!! Its hard to believe that train remain unchecked for such long journey, but mostly passenger too many a times dont care hygiene, as like they dont have to travel/use washroom again..
