this like will be used mostly for goods train unless Y legs comes up at Sarigarh even then loco reversal will be needed at KIR or Aarria-gagalia line completes and Lilitgram station is reworked to avoid loco reversal. even at DBG side, new loop line should complete and DBG-SKI doubling happens. so lots and lots of work needed for this section to be really effective alternate GKP-NJP route !
