In the case of WL not confirm no need to worry, Do 1 thing..reach Station at 12:10 PM (the arrival time of Up train Ahmedabad-Haridwar mail). And take seat in GN no rush to board general..me myself did it on 1st Nov and totsl 13 pssengers travel in GN easily. Just remind that if ur ticket is E-TICKET than buy General ticket because chart prepared at 1:30 so manage 1 person who can buy your ticket
