Hi everyone . An attempt to make daily connection between Kolkata & Arunachal Pradesh. Since Arunachal doesn't have train to Kolkata being a good tourist Destination, I thought a Daily Connection is required. So tourists of both destinations i.e. Darjeeling & Arunachal will be satisfied with good Arrival times at NJP & NHLN. I named this train after 2 great rivers of states i.e. Hooghly for West Bengal & Siang for Arunachal Pradesh Please rate . Suggest changes if required
