Sk has to maintain the PSR of 10 kmph on river yamuna bridge till it passes .
.just after pragati maidaan ...and Telangana don't have to till nzm outer ..if I say according to ur logic ..TG has more unrestricted run than SK for more distance ...But leave it .
Here this video is meant for enjoyment ..so just enjoy .in my trip TG overtook SK ..another trip no parallel at all ..and other trip SK ot TG ..so its upto u to judge what u want to .
