i had already written in blog, Re# 446116-2 "i don't know whether you can get duplicate wait listed ticket or not ,but you can know the PNR number.For that you need to remember your date of journey,your train number,boarding station and "reservation from" station and the booking status W/L number.you give all these details to PRS they will tell you your PNR. (Booking status: suppose for e.g a ticket is W/L 110 / W/L 45 the left side i.e W/L 110 is booking status.It won't change with time)".
I donot know how to send private message
