One problem with running LKO-CNB EMU services is that trains are often delayed[even the few existing services] due to overtakes. Hence, IR should run MEMU trains stopping NOT at the intermediate stations. This will make them more resilient to overtakes and make end to end travel faster. After all, most folks, just travel end to end b/w LKO and CNB and not to the intervening stations.
They can run services starting from LKO, stoppage at Manaknagar, Unnao and finally Kanpur.
