Currently I saw some thing like GNWL in the ticket ( e ticket ) I was confused , I had only known about the waiting list and RAC tickets,
So I found the following list now
now the total system of reservation has been changed in indian railway.
you have more type of waillist and rac now
for example if you receieved just rac that means reservation against cancelation.
if you receive gnwl that means general waitlist ticket
if you receeive rqwl that means reserved quota wail list
if you receive pqwl that means pool quota wait list
if you receive rswl that means railway station quota waitlist
Lets say this is another trivia that might come in handy .
