Its better to change the train timings from VSKP as follows to avoid 1 hour waiting of train between Kazipet and Secunderabad.
VSKP 20:40
BZA 02:40 03:00
SC 09:00 09:20
NED...
more... 14:35
In this case no need for VSKP-SC Garibrath to overtake this train.
Same is the case with Nagavali Express (18309) also
