JP-NDLS Shatabdi face intense competition from the luxury buses operating on the route. Fare and journey time are the key factors here. In order to succesfully compete with them, the Shatabdi need to reduce the journey time as well as fare. So shorter route will lead to lesser fare as well as lesser journey time.
A nonstop Shatabdi with 4 hrs journey time on the shortest route is highly desirable to compete with luxury buses.
