Let's see some facts
BSK gets a better clearance at LKO because it has been running via it since last 10+ yrs. That time slot is fixed and more often than not LKO is able to handle it properly.
GD 65/70 % time gets a better clearance at LKO, remaining time it late, but still is able to make up for lost time post CNB because of it's non stop run in NCR.

one who has lost the most in this whole game of LKO in last 18 months is Vaishali.
Leaving LJN and shifting to LKO has been a night mare for this legend. Still struggles to go through LKO timely.

Also slot is very important thing. BSK is first to arrive at CNB in the lot. Departs before SS. No super fast departs before BSK. So it is mostly able to reach Ndls on time.
Just before getting shifted to LKO Vaishali used to overtake BSK and GD almost 1 or 2 times a week , if they hampered it's run.
But as I said time has put this legend on test.

one thing make it clear in ur head - no Train gets a priority in NCR like it's Prince PR..
Rest all depends on how much time a train can recover, depending on traffic and congestion.
And last word - give a train 4 stoppage in NCR, then matter who u r, u will get thrashed, if u loose Ur slot.

From where did you get this information that BSK is not the most prioritized 110 mps train in NER and NCR?
As we all know NCR means mps & only its homezone train gets full on priority in NCR
Bsk is more punctual then 130 puru & mb
I am not saying that puru & mb are not good they are good train...

& I am a fan of puru & mb but when comes to priority in NCR bsk gets good priority then puru & mb average delay at destination is low of bsk
Keep shiv ganga shram shakti & prayagraj apart because these are NCR trains shiv ganga is of NER but NCR treats it as its home zone train
Puspak runs on different route in NCR
I am fan of vaishali but now punctuality is a past thing for vaishali after shifting it's station from LJN to LKO it looses its priority day by day in NCR in NCR delay gets addup in vaishali because it's stops.
Bsk trolles 130 puru & mb many times in NCR till gzb & oted puru many times if bsk enters in NCR with 3 hrs delay it is constant till destination in NCR it is very difficult to get delay constant for different zone trains.
Gorakhdham express is a good train but when comes to priority bsk gets high priority then this if bsk departs 40-45 late from gkp bsk 95% ot gorakhdham.
See the average delay of trains at destination running on bsk time slot its Punctuality is far better then puru mb gorakhdham vaishali.
Bsk's time slot makes it a high priority train & punctual train of its route.
