It all depends upon the distance, the class etc of travel.
For example PQWL 101 is issued for HWH TATA in Gitanjali and PQWL 87 was issued for HWH NGP and GNWL 10 for HWH CST.
Due...
more... to Berth Multiplexing PQWL 101 for TATA will get confirmed but not for NGP which was PQWL 87. GNWL 10 for CST gets into RAC.
It depends on many things and mere quota has nothing to do with any clearance. All depends upon the distance, sector and booking patterns.
