The Nagore Express that was during the MG days From Kollam to Nagore via SCT, TSI, VPT, MNM, TJ should be reintroduced atleast till Sengottai or Tenkasi as for now.Since the SCT-PUU works are still going on.
SR does not care of Connecting the south most regions.Moreover SCT has been ignored for many years.It needs an one more train to MS.and passengers could be run between SCT-MNM via VPT and SCT-PGTN via POY.
