Rescheduling of this train has become a regular affair for this train. A quick suggestion; avoid this train if u are travelling in AC classes. Better travel in 12314 or 12302 which will ot this train somewhere post cnb and will reach RT due to ongoing clash of 120mps and 130 mps diff. theory.
Paying more and punctuality totally out of question.
A TT change is invetiable so that more time could be given for secondary maintenance at ndls.
