Instead of making coro to leave at 07:00, SER should have made HWH mail to leave at 07:00 am from MAS with the same stops as of HWH mail in AP and orissa to reach HWH around 08:55 am (speeded up) as HWH mail make more stop in AP. (will be more like mumbai mail leaving chennai at morning time ). Then Coro express that arrive 16:00 at MAS should leave as Coro express at night around 19:00 at MAS making ongole and BZA and its stops to reach HWH at 19:30 PM . That would have made more sense with no RSA between HWH mail and coro but still rake being saved.
