Many times i have seen SK crossing Mgs around 0515 hrs and reaching Pnbe 0800 hrs.. On that occasions it crossed Buxar around 0620-0630 hrs and Crossed Ara at around 0715 hrs, and on that occasions the passenger was overtaken at either Bihiya or Karisath.. As soon as the passenger departs from Karisath it becomes a VIP train and no train dares to overtake it.. But on sundays and public holidays it gets overtaken by SK, when it reaches around 0830 hrs..
