If it gets delayed in reaching mumbai by more then 15-20 mins then it gets 0 priority you can go through my trip diary it was made to halt at Vasind for nearly an hour and half from 8AM to 9:30AM it was looped and trains like Mangla, Rajyarani, our mumbai locals etc...etc...overtook it...in the DN direction it gets top priority till BPL only and only train which overtakes it is MUMBAI-NAGPUR duronto but in UP direction it is not given any priority...
