Ya if you Board Single stop bus that is Nayudupet Halt in its entire Journey from Nellore. But for Renigunta you have to De-board at By-pass and have to take an Auto 'Subject to Availability'. What 1hr 10mins to Nyp are you referring to a Volvo. Dude I had traveled several times from Nellore in Early morning what Bus you will get from Nellore to reach Renigunta. You should have to use some Buffer time also for Riskless Journey.
