RLWL i.e. Remote Quota :
This is also known as Running Line Waiting List or Road-Side Location Waiting List.
RLWL means Ticket is issued for intermediate stations (between the originating and terminating stations) because usually these are the most important towns or cities on that particular route. This type of tickets will be given a separate priority and confirmations will depend on the cancellations of a destination confirmed ticket, and these tickets don’t even have RAC Provision. For this type of ticket there are less chances of confirmation.
PQWL...
more... Pooled Quota :
This is a waiting list ticket against pooled quota. It is shared by several small stations in a particular.
The Pooled Quota is intended to be utilized by passengers travelling from the originating station to a station short of the terminating station, or from an intermediate station to the terminating station, or between two intermediate stations.
Note: In some cases, where the station shares less quota, it can be clubbed with GN Quota after Gh N Quota exhausts and/or to exhaust the PQ Quota.
