People want Chennai and Hyderabad connection from Jabalpur. But
Something is better than nothing nowadays atleast they're considering a train to South from Jabalpur. If they ran it via Chennai then whole Tamil Nadu and Kerala could've been covered (because of connectivity from Chennai).
More takers for Chennai than for Tirupati from Jabalpur, Railways will have to understand this.
Now if they give it...
more... a stupid time table and low priority then this train could become a flop too.
