It gets Parcel Van attached/detached @ NDLS (same like in Himsagar & Andaman Exp)!!
The attachment makes 150 Min stop, while detachment makes 55 min stop @ NDLS!!
To facilitate the slack timing has been introduced for NZM Stoppage & consequently run-time in between NZM-NDLS (in case PF wasnt empty or it takes more time for all this activity)!!
