Make such a monumental change in any train like the one done with this train, then we will see the kind of impact it has on that train's punctuality. I agree it was very dis hartening to see it running late, but if u see it's run from 25th march onwards, it was late but consistently arriving by 8.30 am at NDLS.
Bring any train late at CNB by 1.5 hrs daily, give it 4 stoppages in NCR and see how it gets ruined.
