Sir, Its SR's gimmick to fill DD. Even before DD was introduced atleast an year before 22625 started running, Brindavan's departure was changed from 7:15 to 7:50 AM. The current schedule which DD follows is the original schedule of Brindavan which used to arrive SBC at 1:30 PM. And now Brindavan has been slowed down even more. The old TT was faster when compared to this TT in terms of duration. Regarding patronage, Brindavan's AC coaches never ran empty even after DD was introduced. It was the DD which ran empty inspite of Brindavan's TT. That is why, SR took this step. And they reduced 2S coaches so that those reserved 2S passengers also shift to DD. That is why DD is successful. Otherwise, it would be half empty. When DD was introduced, only 2-3 coaches were full. So, its all planned by SR as it could see that Brindavan's AC...
more... was getting patronage even after DD's introduction.
