PQWL stands for pooled quot waiting list. There are many different types of waiting lists on reservation tickets. They are GNWL, CKWL and PQWL. The seats in a train are divided among these waiting lists. Some of the trains have pooled quota waiting list.
The pooled quota waiting list is applicable to intermediate stations and is shared by several stations between the source stations and the destination station. Passengers who’s journey starts from intermediate stations are likely to get their ticket in pooled quota waiting list.
Well some says that its more chances are there for the ticket to confirmed if its in a pooled quota waiting list and the others contradict this.
My experience is that the ticket was not confirmed. If you have any experiences, you can share here by commenting.
