Bro currently BBS Durango travel time is 31 hrs. Let's say suppose it will be extended to VSKP and converted as duranto. Then it will have 38 hrs travel time
If a new rajdhani is introduced
It will take 28 hrs travel time via BZA route
It...
more... will take 26 hrs travel time via KMZ route
It will take 27 hrs travel time via CNB route
In any of above 3 routes it will take 10 hrs less travel time than BBS DURANTO
Then why would any one prefer this to extend
