Tickets are booked within few minutes as soon as the booking opened. So, book a ticket on a IRCTC website is a difficult task.

When you are on the Indian Railways website (irctc.co.in), click the button in your bookmarks to fill the reservation form with one click. And all passenger details will be filled automatically.
