I think railways must ensure following to ensure timely run of this train..
1. It must be given an Wap5/7 upto patna for better acceleration as it has got man stops enroute..
2. From patna a WDP4 will do the job..
3. An extra rake should be provided.
4....
more... Railways must create an committee or form a department to look for delays..
5. The priority must be increased.
