* Connectivity of Cities like MDU, TPJ, RMM etc with other than South India is poor. Since the southern vertice of GQ i.e. Chennai is located at north tip of TN, Rest of TN does not get benefit of better connectivity normally available in GQ route.
* The benefit of wide range of new connectivity enjoyed by major guage converted routes like DLI-ADI have not been given to MS-MDU-CAPE/TEN route. Today JP, JU, AII, BKN, UDZ etc are connected to almost all the region of India after guage conversion. The same is not true for MDU, TPJ etc. forMay be the HQ located at MAS is not taking enough interest.

(1) Extend TN or GT or TNSK (make it daily too) to Tirunelveli/ Kanniyakumari via Trichy/MDU
(2) Similarly one of the daily train coming to Chennai from Mumbai, Kolkata etc should be extended southward
(3) Some of the weekly trains coming from farflung places to Chennai too may be extended to MDU and beyond. Introduction of a new BSP-MAS weekly SF a few years back is a surprise, it should have been BSP-MAS-TPJ-MDU-RMM.
