I did a mistake. But just see the TT of 12957. Spd 107 from jp to ggn ? IRI has calculated wrong. 277km in 3.30hrs takes to 79kmh avg. and not 107. I refered TT of swaraj from BDTS to BRC, adi shatabdi from brc to adi, sj rajdhani from adi to ndls, shri shakti express from ndls to uhp, malwa superfast from uhp to svdk.
