I want to know sites which offers to check seat availability in simplified way. I have tried Indian Railways official website but its ask for source and destination station code, which i don't know. So, suggest me any site which shows the result on providing train number only.
you can use erail.in.....u will be able to check with source/destination by giving the name of city/station and selecting it's code...
You can check the seat availability of your train before booking ticket to know whether seats are available in your preferred class by visiting train seat availability page.
