02510- the express you are talking about terminates at BNC and not YPR. Always in SBC region, any train going towards YPR from BYPL side will have an additional 45min-1hr hour slack compared to trains terminating at BNC or SBC as BYPL-YPR line is single. but yes, even then 02863 has an extra 1-2 hr slack after KPD...I guess they will make all the major SR/SWR trains to pass JTJ ahead of this train..
