If you have to take a train from MFP/GKP to DLI, this train should number one on the priority list. The reason is quite simple. While trains through CNB-GZB route get delayed due to high congestion, this skips the crowd through the LKO-MB-ANVT route. Adding to this well known fact, MB division gives very high priority to this train. It has overtook nearly every morning train on the section when late. This is precisely the reason, even in dense fog conditions this has made it to Delhi not later than 1 PM (that too rarely).
