For that there has to be a train with early morning arrival at BHNG .A Kolkata to Murkongselek train with slips to BHNG can be prepared.Rake can be splitted at Balipara.As we have seen the population in these areas are splitted,So it is not really possible to give trains to each and all.So trains need to have slip arrangement for places like DKGN,NHLN as well.
