The official PNR status application is the only app that provides a comprehensive view of all railway stations. You can check the status of your train in real-time. You can also find out the status of all trains running in India and find out when your train will arrive at your station. You can also get updates on the latest schedules and routes. You can also find out what trains are running between any two stations and how long it will take to get from one station to another.

The best part of this app is that it is free and that you can use it without any login or registration.
