For this train, SL class quota from TPTY to GNT is GNWL upto the end of 2012.
Suddenly in 2013, why is this changed to PQWL which is inconvenient for the WL tickets to get confirm. Check the below entries.
2012 - /pnr/post/614684
2013 - /pnr/post/805234
What...
more... is the criteria for changing the quota from GNWL->RLWL->PQWL or vice-versa?
