DHN-Telo-CRP-BKSC line has already been announced. RITES has submitted the reports regarding it which also has been approved.
And DHN wont let go of its Shatabdi to Ranchi-HWH despite having plenty of options.
But a new train can be given via Kandra-Namkom line not necessarily a Shatabdi.
Besides HWH-PNBE has a Janshatabdi so which runs quite empty.
