Online feature for railway ticket booking by Indian railways is so helpful. I always book tickets online so its get easy if I want to cancel ticket.
Also app send us ticket in email as well sms to registered number and at time of journey we to just saw that ticket on Mobile no need of any print or hard copy.
App saves all previous and current ticket and payment method is so simple it provide debit card, credit card, paytm, freecharge, mobiquik amd more options. Also IRCTC prepaid wallet is there for fast checkout as we have to save money there as wallet.
