If VS have intercity than have option for same intercity DUMKA PATNA can run almost VS time why this good train making ECR in like intercity/fast passenger. If not diverted than no have any chance for speed up. PNBE to KIUL i seen many time to overtake any another SF train. Why this train h name SF better After PNBE can make SF BGP to PNBE same like intercity. and this Diverting not only demanding in KG line.If you asking all passenger BGP to KIUL also aggre for diverting and speed up KIUL to DDU . bcz everyone no this train good running after DDU without any passenger seat issue.
