The equation from NCR is simple for Duranto
Cross Prayagraj almost on time and cross Cheoki before 02149 departs.
Otherwise you trail behind 02149 and at the end it is mostly looped at Jeonathpur.
NCR also wants to hand the train to ECR which is running on time because that will boost its Punctuality report, rather than delaying each of them by...
more... few minutes if they trail behind Duranto
