Atelast a better option than staying in WL.
The passengers can travel additionally if they can persue the SL 55 berth holder(if not given as RAC), they can adjust for a night.
I think this should be Stamped as CONFIRM bcoz irrespective of the partial confirmation, the passenegers can travel to their destination.
But...
more... we stamp it WL which would at first sight seems the ticket is in WL and WOULD NOT BE able to Board the train.
