I have just made a railway booking from Delhi to Mumbai on the Suvidha AC Express, and after making the booking I see that my seats are on waiting list, WL is stated by the status. I have just paid the full amount for the tickets, so why is it on a waiting list. Unless I am not understanding it right, can someone please explain what is waiting list in Indian railway reservation? I am not from Delhi or even India and will be coming from Malaysia and I don't really want to be stranded at Delhi airport. If I am right in thinking that I will only get a confirmed ticket is someone else cancels, then I have a few queries. 1. What happens if I don't get a confirmed ticket? 2. Do I get a full refund back? 3. What is the earliest time I can find out whether my ticket has been confirmed or not? 4. What other options would I have to travel from Delhi to Mumbai?
