NCR - maar bhi, raftaar bhi - Harshit Sharma

You want us to find logic in diverting already significantly end to end patronised Premium Fully AC Train from a Geographically far off and weaker State to the National Capital of the country that already has lost it's other dedicated connection to a city beyond the National Capital in name of Politics.
All of the above in favour of City which won't even get 100 seats in the aforementioned train, will add significantly to the running time and already has a fully AC Weekly option in form of Godda Humsafar alongwith Daily Connection. Also, I don't think Naugachia halt for Dibrugarh Rajdhani is because of Naugachia being Naugachia- more due to Naugachia being near Bhagalpur 😂.
Which...
more...

simply means ego satisfaction by having Rajdhani at Bhagalpur Junction.
Yeah that seems to be the summary here. Also I have missed a great many things to add.
Now YOU TELL ME why don't you want Dibrugarh Rajdhani via Lucknow as suggested by many others ??
