As per me,its the best train to travel from secunderabad to odisha/kolkata.
Personally many times travelled in this train. From secunderabad to vijayawada,its good speed,punctual and no unauthorized entry. After BZA,some local travellers bound to inbetween stations of BZA-VSKP board the train but here SCR TTE are very strict to this and they don't allow to board them in sleeper classes. So till morning i.e berhampur,its all neat,clean and happy journey. But after that,the journey till BBS sucks. Train is bit slow and unauthorized pax board it to go BBS/CTC. TTE also don't even ask anything. After BBS/CTC,again this train shows its full aggresion. If falaknuma exp gets late by 20-25 min at BHC,then hold your breath for a deadly aggresive overtake...
