Help me nagpurkars..

Hi, from my childhood I loved trains and still I m fond of it. Is there any spot in nagpur where I can just sit and chill and watch the trains on main lines like Kolkata- Mumbai or Delhi- Hyderabad ones. I used to do it earlier by going at ajni station like once a month but I need the spot where I don't have any people around me just to chill 1-2 hours.
