1) AMI/NGP - CSTM Weekly Overnight or Day (Sitting) Superfast departing on Sunday and retun departing on Friday. The rakes of AMI-NGP Intercity can be used for that.
2) NGP-BSL (via WR, BD, AK MKU) Janshatabdi or Intercity (Day train) for daily passengers between intermediate stations. This can also be augmented with a slip train as BSL-Ballarshah to go with another express from Wardha/SEGM till BPQ.
3) AMI-Pune (via BSL, MMR) SF Express is a must, atleast on Sunday.
4)...
more... Amravati - NGP Intercity can be extended to Gondia.
5) A Slip SF Express Narkher-Mumbai on the ground of 12139/12140 Sewagram Express. This train can be run as Narkher - Amravati (not NAVI) Passenger, can be attached to 12112 AMI-CSTM SF at 6:30 pm to go with it. 3 SL and 1 III-AC can do. AMI station PF's can accomodate 4-6 more coaches for 12111/12112, but don't know why railway authorities are not increasing coaches of this train.
