Here taking about via new line not via ctc
It wasn't mentioned about the new line anywhere in the post though. Hence I thought via CTC
Dada DHN-DIGHA overnight train not at all required. Will get less than 10% occupancy. Instead DHN-PRDP exp via Tatanagar will get good patronage. See Dhanbad, Bokaro, Tatanagar, Hijli/ Kharagpur, Bhadrak all big stations and Dhanbad, Bokaro, Tatanagar r Industrial cities. Many officers, workers, labors travel between these cities. Also Paradeep has many industries. A Weekly special train with suitable TT can be tried and if gets patronage can be thought i think. What is you thought Sir?
I know these two are of inverse nature. What I meant is relevance for the population you're targetting. Santragachi-Paradeep is already dump. When a metropolitan completely fails, we cannot expect tier 2 cities to perform any better. 90% of the employee base of Paradeep are from northern India like most other central industrial hubs here, which hardly have any mutual connection. In such a case connectivity to deemed destinations described by the host company(s) is of only relevance. For eg. ANVT-HLZ Exp, Haldia inspite of having ~60% local working population provides good patronage to this. Same weekly result can be expected from Paradeep as well.
