Aaj kal SG ki priority kaafi zyada hai, both UP and DOWN, not denying the fact that SG has priority since it's inception.
In UP, it usually escapes from OT of SK which is another prioritized 130 SF and even overtake 110 and 130 SF in its run.
In DOWN, it denies OT of SDAH duranto, ruining it's run showing it's priority.
Overall you...
more... can't compare one train with another in overtaking each other as it is usually priority based controlling in NCR and not the other factors which are sometimes provided by members or even officials.
