I want to express my happiness at the extremely useful way in which I could use this site yesterday for reservation.
I needed to change my travel plan to a late evening train while already having an afternoon booking for 2 of us. The travel date is 4th May. Every train showed hopeless numbers against WL. I learnt 2 things from PNR forum:
i) that if I buy for a longer distance I might be better placed for a confirmed ticket
ii)...
more... that selecting the right train can enhance the chances of confirmation.
Armed with this I searched for the SS Quota that is applicable and IRI interface showed me all the trains where confirmed ticket was actually available though the General reservation showed hopeless position.
I could get 2 confirmed tickets for AC 3 Tier under SS quota for an extra cost of Rs 300 for a longer distance of travel than required.
This interface is not available at irctc as well as indianrail.gov.in.
This interface is invaluable. I thought I should thank all of you for this.
