SY/CDM people will not go to MV to board MYS-MV express. By bus, CDM-SA is only 5 to 5-1/2 hours. You want them to travel by bus 1/2 - 1 hour to MV and board the train which will take 7 hours to SA, through a de-tour. Such "Darshan/ Tourist" trains are run in SWR. Why to make such things in TN also? Requirement is simple - a direct convenient train from SBC to Delta region upto MV/KIK/Nagore/VLNK.
