Indian railway and catering tourism corporation( also known as irctc) is a website which allows users to book tickets online.
It also delivers I tickets which are just like the normal ticket and are sent to you through post.
It allows users to reserve seats and book railway tickets online.
I have been using this site since a year for booking tickets as buying tickets locally can be a bit difficult. Online ticket ordering is very convenient to the user.
Overall, it is a very good site which allows users to book tickets and even check per status. I would definitely recommend this site as it provides hassle-free tickets!
