Yes we know bhai since we also belongs to SCR only and that too GTL ,we have already train connected with patna from SC, so my suggestion would to request this train from SCR since SCR region will fall near to Bellary so instead of running from bellary i am telling better run from Hubbali since SWR zone may or may not have plan so SCR can initiate this.
Also we have double track on this route from hubbali.
