Sir SRC-PRDP exp is a dump because of Railway Commercial failure. A train given by ECOR and RB only to use the RSA and for the sake of giving the connectivity with Kolkata. But a commercial failure.
Haldia and Paradeep are very similar , both have Industries, both have Ports. Both Haldia and Paradeep are underutilised stations of IR in terms of passengers traffic. Paradeep is pretty new but Haldia is used only for Freight loading for years by SER. In Panskura-Haldia route Freight has higgest priority and EMU trains. Some situation improvement now but till years before if was the situation. Both Paradeep and Haldia passengers prefer Road transport over Railway.
You...
more... r correct Haldia gives passengers to HLZ-ANVT Exp because the reason i say is in Factories, Ports workers , labors r mainly from Bihar, Jharkhand, other parts of West Bengal also from many Southern India states. To cater these you remember RB approved HLZ- MAS Exp and HLZ-ANVT Exp. Because many workers, labors are working in HALDIA PORT , and different Factories, Refineries of Haldia r from Bihar, UP, Jharkhand, Andhra, TamilNadu, Orissa, other parts of WB also. To give them benefit these trains r given. Even HLZ-MAS Exp gets passengers from Haldia for that reason.
Now comming to SRC-PRDP exp, if you see many Factories, have Regional offices in KOLKATA as Eastern Regional Offices also many have Offices in Bhubaneswar. Also, Paradeep Port and different Factories, Refineries in Paradeep many labors, workers, officers works are from Bihar, Jharkhand, Orissa, West Bengal. Many officers also visit Paradeep from Kolkata office or Bhubaneswar office for Site visit at Paradeep. If you remember many years back different Industries there at Paradeep had submitted many Proposals at SER HQ, ECOR HQ to provide a Connectivity between Paradeep and Kolkata, Paradeep and Bhubaneswar. But unfortunately ECOR gave connectivity but poor TT and not suitable to any passengers and without survey of passengers needs there. An Tri-Weekly Intercity day train with CC, 2S, II was needed instead of 2A,3A,SL coaches train and because of that failure SRC-PRDP exp is a dump now. RSA partner was given priority not passengers needs.
