Apne slot per..?? SS shows that in last 30 days only 9/8 times these respective trains have reached CNB before 00.00 hrs...So these trains don't run in there slots from CNB most of the time... Hope u got the point.
I know very well that they get delayed between MGS-ALD-CNB section...But, this is the reason for them not running in there own slots..The fact is they run in other slots and try to cover as much delay as possible in CNB-GZB section...Another fact is that both MB & Puru are able to unleash 130 factor in CNB-GZB section mostly.. Barring SK, none of the 130kmph upgraded trains are having that kind of run in MGS-CNB-GZB section.
