starting from Nagpur is not possible because NGP is in CR and SECR can not have privilege to start train from there thats why SECR terminates train at Itwari iteself remember one thing TATA NGP Pass which previously go to Nagpur degraded by CR and its now limited Run to Itwari still at TATA its announced as TATA Nagpur Passenger, but it not goes to main station of Nagpur, so if want to start the train then only have a possibilty from Gondia Itwari doesn't have Pit lines all its coaches from SECR maintained at Gondia or Bilaspur came with ITR R BSP Pass.
