Vaishali doesnot gets priority in NCR,see its Arr/Dep history,Gorakhdham regularly gets overtaken by BSK near Basti or Gonda,Shram Shakti gets priority but not that BSK gets.BSK is the ruler of NCR,many times it has overtaken Purushottam and Poorva also despite of that both these trains are 130 sanctioned.No train can match the priority of BSK in its time slot.
