Once the tickets from the Pooled Quota is filled, PQWL tickets are issued. Chances of PQWL tickets getting confirmed are usually very low, as in the priority list of waiting list tickets it comes after GNWL.
IRCTC Refund Rules of Waitlist TicketsAs per IRCTC refund rules, if you have a Waitlisted e-Ticket (GNWL, RLWL, or PQWL) and its status remains the same even after the chart has been made, you will be refunded the fare automatically by IRCTC after deducting applicable fees.
If you have a PQWL ticket, it means you are on the waiting list for a specific quota. Whether you can travel or not depends on whether your ticket gets confirmed before the journey date. If your ticket is not confirmed, you may not be allowed to board the train.
Chances are very less as i have my own experiece with pool quote waiting list aka pqwl. Its very rare to see this get confirmed. It also depends on the route you are travelling,the season and the class. You can try confirmtkt website to check the confirmation chances.
PQWL tickets are distributed once the Pooled Quota tickets have sold out. Confirmation of PQWL tickets is unlikely because they are lower on the priority list than even the GNWL tickets.
