As it is, this is a fast passenger. If required, ask for separate trains from VLNK to QLN (revival of earlier MG era train Nagore-Quilon Exp/FP) or KIK to TVC via TPJ, MDU, NCT.
Due to space constraints at TVC, KCVL has come up, but it has to develop. Few other trains are sent out to NCJ (Parashuram, Ernad, etc.).
