SG is certainly high priority train but ye 2 times HS se OT ho chuki hai. Once by 12596 and once by 12571. Abhi kal bhi HS SG ke kaafi kareeb aa gayi thi and was at a gap of just one station jab fog restrictions lag gaye aur SG bach gayi. But morning me aap dekho 12571 ne NR entry ke waqt SG ko lapet diya tha. Still I have high respect for SG as it too is pride of our NER
