In a twitter query recently, Sr.DOM HYB divn has replied saying that a passenger and an express train is soon to be introduced in NZB-KRMR-PDPL section but did not specify if its going to be an extension or a new train.

Personally i interpret it as an extension of both trains(TPTY-KRMR to NZB and LTT-NZB to KRMR) and introduction of a new passenger train. In all likelihood extension of NZB-BDHN-NZB pass to KRMR is not likely since the arrangement is that three coaches of NED-NZB pass are swapped in the night at...
more... NZB and the three coach rake runs as NZB-BHDN-MZL-BDHN-NZB pass and the three coaches are again swapped ith NZB-NED pass every night since NZB does not have a coaching depot, this rake is maintained at NED CDO.

Perhaps some RSA for a passenger train or more will be worked out eventually with KCG CDO or SC CDO to inagurate more trains in this section, lets wait and see.

Also finally, although based in bangalore but originally being from Bodhan myself i also wish to see more trains in this section and have been writing numerous PG portal or RTI based suggestions/information requests and closely monitoring this section construction from years, the launch of this stretch seems to be done in a hurry to prove political achievements and staffing of all stations enroute and infrastructure still is in the initial stages. Having said that, this stretch is an important part not just for passenger connectivity but for freight transport in terms of coal so lets wait and watch, according to SCR more pass/exp trains are to be inagurated soon.
