I understand that online purchase of tickets are available 60 days in advance at 8:00 AM. I just bought three tickets from NDLS (New Delhi) to NJP (New Jalpaiguri) on the Dibrgarh Rajdhani at 8:00 AM on October 26, 2013 for a journey on December 25, 2013. However, it showed only two first class tickets available under general quota. I don't understand how can only two tickets be available in a train for first class just when the purchase option is opening at 8:00 AM? Therefore, my own and my wife's ticket came as confirmed but my nine year old son's ticket came as RQWL 1. What does this mean and do I have to refund these tickets and buy something else?
