Bro.. I really doubt they will give one more train to Tuticorin. The specials that SR runs now are either to TEN or NCJ and none has been to Tuticorin. I really don't think Pearl City does has the same demand when compared to Podhigai, Nellai or KK. If they do start another overnight train from SCT to MS via Mainline with GNWL till MDU this may reduce the load of MDU passengers in other trains..
