Today, 139 is the one nation-wide enquiry number to call for all railway (train) passenger enquiries in India.
Just call 139 from any village, town or city in India (without prefixing STD code) to get information regarding all basic train enquiries like PNR status, train arrival & departure, accommodation availability , fare enquiry, etc.
(And some other important things to note.)

- Driving Licence
- Vehicle's Certificate of Registration (RC) 1
