What is the difference between e ticket and i ticket in Indian Railway reservation system? For the first time I am trying to book tickets for my train journey through IRCTC reservation portal. And I can see that there is option to opt for either an e ticket or i ticket. I am presuming that there must be some fundamental difference between the two types of tickets, but I could not find any relevant info on the IRCTC website. Which one would be applicable in my case? Which type of ticket shall I buy for my travel? Can someone possibly throw some light on the difference between an e ticket and i ticket?
