Connection between district of North Bengal and South Bengal.
Intra State connectivity is solely dependent on Kolkata. Every travel to other district has to be through Kolkata.
People from the district of CoochBehar, Alipurduar, Jalpaiguri, Siliguri dont have daily Intercity connection with the districts of Bankura, Medinipur, Purulia and Asansol-Durgapur.
All have to come and deboard at Bardhaman for trains to ASN/DGP...
more... Or come till HWH.
Thats why if a New CoochBehar Asansol Kharagpur Express (Via RPH SURU DGP ADRA,maintenance at Alipurduar Jn) is started it will provide sort of overnight Connectivity.
