If one more rake will remain in spare, so one more train can be started as Indore - Amravati Express or Indore - Akola Express via NRKR, CNDB, NAVI or via Nagpur. They can start it either as Day Time Intercity or an Overnight express.
As Akola, Amravati people are having good trade-relations with Indore... the train can receive good response withing short time.
