CNB-AGC & AGC-JHS was the reply against possible travel option for CNB-JHS (for this train)!!
Its just 1 of 3 weekly connectivity option for AGC/AF towards Okha, with add-on to few limited options to ADI even!!
Its not just ICE type connectivity & sync with the line of heavy WL route of existing train..
& yes, with CNB-JHS getting dual & Elec, the route will open gateway for SF induction sooner!!
But that doesnt mean, train with long run doesnt address passenger need/requirements!!
