Boss 7:40 NDLS ARR: Only one reason exist & that is * BPL-JHS: Scheduled OT by 02171 & trail 02171/08215 (Ex JHS) til NZM.
If this isnt corrected, OT in BPL-JHS by 12171, 22455 keep Boss to trail 12171, 22455, 18215, 22867 till NZM.
Solution: If 12171, 22455, 18125 speed-up & follow 22867 TT in JHS-NDLS (NZM ARR 6:10, quite impossible) to make TN ARR NDLS @ 6:45, just after AP!!
