That day unfortunately Pinakini got stuck at Singarayakonda , it was standing there for 90 min due to some track work I suppose . And thn Pinakini got late by 2 hrs . Because it had to terminate at BZA while other following trains were going long distance with strict schedule so they had to loop Pinakini .
Not sure but when Sangha crossed Ongole , Pinakini was quite ahead and could have managed to reach BZA.
