As Simhapuri is having uneven Timetable in between Gudur and Vijayawada this train is getting daily delay to vijayawada but from there it is going good. Because of this unevenness Padmavathi is also getting delayed which is running just 5 min beyond this train.
It is very difficult to manage trains within 5 min gap because Simhapuri is having lot number of halts in Gudur- vijayawada section whereas Padmavathi is not having much having halts but in Vijayawada-Secunderabad section simhapuri is having less halts compared to padmavathi. Both of the trains are getting affected.
