So its an ICF Mail-Express kind of train that will run between Kolkata Chitpur and Lucknow via Patna. The stoppages aren't too much on the Main Line Route when compared to the Kolkata-Patna Express which is the combination of Lal Quila & Janta Expresses :)
.
PS: This train can run on a Bi-Weekly basis so that if its made to run 1 day via Patna then on the other day it can run via Dhanbad - Gaya :-D
