rules say no WL passengers are allowed to travel. but TTE on board sometimes allows passengers with partial confirmed passengers - provided you do not ask for any extra seats and adjust within yourselves. berth charges are taken but not provided if not available. before boarding, pl request tte for adjustments option. generally they allow. maybe in case of raj, duronto they may not.
pl check with tte before boarding for many unpleasantness can be avoided.
