For that they can introduce Rewa-Bdts/Bct express via sgo-bina-bairagarh. This will give connection of Rewa also for gujrat and mumbai.
If jbp-bdts diverts via sgo then railway will make it bypass bhopal which they are doing for every new train on bina ujn route. This will lead to bhopal loosing another good connection to gujrat(Surat, Valsad) and western mumbai so change in route of jbp bdts is neither feasible nor profitable.
