A Waiting List Ticket (WL) is issued when there are no more reserved seats available to be booked.
1) RLGN: Remote Location General Waiting List (RLGN) is issued when a user books a ticket where WL quota is RLWL.
---This means after ticket booking RLWL gets named as RLGN.
2) RSWL: Roadside Station Waiting List (RSWL) is allotted when berths or seats are booked by the originating station for journeys up to the road-side station and distance restrictions may not apply.
---This waiting list has also very less chances of confirmation.
3) RQWL: If a ticket is to be booked from an intermediate station to another intermediate station.
---If it is not covered by the general quota or by the remote location quotas or pooled quota, the request for the ticket may go into a Request Waiting List (RQWL).
