I am planning of creating a IMG WBSK from NOQ to ANVT due to following reasons:
1) Districts of WB covered - Alipurduar, Coochbehar,Uttar Dinajpur, Malda, Murshidabad, Birbhum, West Barddhaman ( 7 districts , 7 stops)
2) It can connect major tourist Destinations & industrial cities of Bengal like Dooars Region, Darjeeling hills, Tarapith Mandir, Durgapur Industrial belt through One train.
...
more...
3) I thought of Sealdah to Delhi via Sahibganj Loop but that was not beneficial .
4) The stops will be decided in such a way that one station can be useful for people of 2 major cities to board this train .
If you don't agree then comment a better route. I think no other route has capability to cover WB in such a short way except Kolkata to Delhi one
