H1, A2, A3 are not required. The train runs in daytime from Tirupati to SC and even in reverse direction. So the empty berths at SC will not be filled for onward journey. Second the train travels one night and day to reach NDLS at evening from SC with 24 hrs journey while direct travelers are preferring to travel by air from Hyderabad either they can opt for evening flight or early morning and can save the day for work or spend with family.
