Feels like just a gimmick to have it originate from ANVT when it is going to take such a long route.
The major benefit in my view, is the direct connection from VSKP to pilgrimage areas in Bihar and UP. In that case why aren't CNB/LKO considered as source/destination for this train. 34 hours from VSKP to Delhi will not be preferable for those going to Delhi.
I...
more... believe it would be better to have a direct train from VSKP to Delhi via Katni, Saugor which will take far lesser time and hence will receive good patronage from Delhi-centric public. An alternative could also be introduction of BAM-NZM train via VZM, R, KMZ.
