Cannot understand the TT. It has only 5 minutes halt at Barauni which clearly tells that it will get diesel loco from RNC till KIR. but Loco reversal is required at Barani Jn in order to follow Barauni-Katihar section. Is it taking the by-pass before main Barauni Jn railway station and halting at other Barauni railway station which i can see in the map.
