The only solution to the situation and to overcome the present situation is to handle train with good flexibility and regulation of trains should be done wisely (sticking to TT). Popular trains should be augmented with extra AC coaches.
Providing valuable priority to trains are also very much needed to handle trains running in time.Automation of PF allocation can also be considered as a solution for running trains timely.I suppose to greater extent if possible IR should start working on 3rd track between CNB-NDLS-CNB.
