There are only 2 trains from nellore to delhi/agra/mathura. And one has remote location waiting list.one must travel to tirupati/chennai/vijayawada to travel to NCR. If TN and garibrath is provided stop at nellore it will be helpful to south coastal people to travel to NCR.
Is only GT enought to satisify needs of south coastal people to travel to our nation's capital?
