BAM to KUR/BBS, there are huge numbers of trains running. Ganjam berhampur area people can come easily to KUR or BBS at any time or else they even have the option of hirakund express which is 4 days a week. Railways can't provide dedicated trains to all districts. In odisha there are still many places who have never seen railway lines, atleast berhampur has got great connectivity in two directions i.e north odisha and andhra region. So start looking for option instead demanding a new train.
