As far as I checked there is no problem in track route
I think this is happening because earlier some part of Gondia - Balaghat - Nainpur - Jabalpur route was under gauge conversion
IMO...
more... let this setting of shortest route be as it is because currently passenger trains are not running in this route after commissioning as BG section even though it is shortest route
I said to change setting of shortest route later because if
#moderator sir changes the setting now then route of current special trains might get affected. To correct the route TLs must be updated. So it is better to postpone to change the setting of shortest route
So let us wait for IR to introduce passenger trains in this section. After that moderator sir can change the setting of shortest route
