I guess the rush would have happened and new train got added since at the very last minute seems another train 02522 Ernakulam-Barauni on the same day (5-Nov) going almost towards the same sector got cancelled because of some works between Kazipet-Balaharshah section. Instead of cancellation, they could have looked at diversion at least. Cancellation notification of Ernakulam Barauni from DRM TVC attached
