its an old thhinking of NCR fans ..AS normally now its impossible for purushottam to be overtaken by any non 130 mps train ..
its just blessing in disguise for ncr fans by thinking this kind of overtake..
puru take approx 1:30 hrs to enter cnb and exit cnbi where as it merely takes 30 mins for 12276 to bypass cnb ..they dont know the difference ...btw an overtake and a bypassing .. old prblm not der fault ..
