I have been travelling from madurai to kurnool for the past 3 years, but never experienced such a bad journey. Instead of arranging a single bus for the entire journey, they arranged a bus from the starting point to Bangalore & made all the passengers to swift to another bus at 2:30 am for the remaining part of the journey, thereby disturbing sleep in the middle of the night. This was done without prior information.
The sound system was not good. This bus doesn't have sockets for charging mobiles.
