This will be useful as a train between MYS-SBC. 16526 takes more than 11 hrs to reach ERN. MYS to SBC another 3 hrs. So total around 14 hrs. From MYS one can go to CLT (by road) within 4 hrs and can catch a train to ERN and can reach by 4 hrs. So total time will take around 8-9 hrs. Don't think so much useful for passengers from MYS to ERN and further.
