I concluded 60 mins slack because in both the directions it did the same... easily covered up 60 mins... actual timetable is of 7.5 hrs n they always add necessary slack so that train in any case shud cover up n be on time. Madgaon terminal would have been a minus point here as my 22119 was 55 mins delayed still krmi arrival was just 8 mins late... They got enough time for sec maintenance of cleaning. Had this been mao terminal the delay cud be more. . So, the timetable is properly planned including krmi terminal over mao. I stick to my point it has slack of 60 mins overall which is a good thing
