Currently KGQ SRR stretch is covered under 4 hrs by the two VB with an MPS of 110 kph in this route. Except the Walayar Ghat Section, the remaining stretch once upgraded to 130 kph, could do justice.. I am not claiming it will cover the stretch in 8 hrs, even a 9 hr TT would work wonders. The fastest train between Mangalore & Bangalore takes 9hrs 15min via Hassan if I am not mistaken. If VB from MAQ to SBC via Hassan comes with reduced TT, its well & good .
