Once you cross Guntur it is hard (not impossible) to find any food items or water bottles for supper in upcoming stations. So better prepare before or at GNT or bring food from home itself.
dont know about nandyal(about food catering), dhone has canteen but it is odd timing
All coaches are new and all have a charger socket.
Charger socket in each bay or near the door?
Jay The Traveler: As name indicates you are going to set record of using all trains of India or Most of them. So far how many trains you have travelled? and which trains you liked?

I have traveled in many trains but never kept track of them. Number one for me is Tamil Nadu Express. I know standards have gone down but still my favorite. Haven't traveled much in Bihar and UP. Second best for me is Rani Chennamma Express and third would be Coromandel Express.
Charger socket at each LB and SLB of all SL coaches
