Next move should be to extend one train each originating from TVC and MAS upto Murudeshwar or Karwar.
2 night trains (Malabar and Maveli) and 2 day time trains (Ernad and Parashuram) have PM at MAQ. Also Maveli/ Malabar have RSA with MAQ MAS Mail and West coast express. Ernad has RSA with MAQ CBE ICE. Meaning 7 trains are having PM at MAQ.
It would be better if one TVC train and it's RSA MAS train can be extended to MRDW/ KAWR by shifting PM to either TVC or...
more... Chennai, Karavali will get very good connection to TN and KL.
With the freed up PM slots, SR can run a tri weekly to TPTY and tri weekly to MAS via HAS SMVB.
