LKO-NDLS (via MB, Diesel route) + Its traffic = LKO-NDLS(via CNB, electric route) + Its traffic
Run time of 12229, 12429 > 12553, 12565 !
Even runtime of 14207, 12557 ~ 12225
In my opinion, after electrification of GZB-MB route, few non stop train between NDLS-CNB can be diverted via MB. CNB people may not have much loss for 12225 and 12553/65 (anyone)
