This video is clearly wrong , nice capture but mathematically speed comes out to be 132 KMPH.
Number of coaches = 21
Length of LHB coach vestibule to vestibule= 24 metres
Total...
more... train length = 504 metres
Time = 13.66 seconds
So , speed = 504 / 13.66 = 36.896 m/sec = 132 kmph. ( slight overspeed or frame loss probably)
