Falaknuma express, only good because of its time suitability, punctuality don't know, it was rescheduled many times due to rsa with Ajanta exp, travel experience can be worst currently due to Economy Ac coaches, and whatever appreciations are given in Wikipedia like about cleanliness and punctuality, currently it is not visible and even halts have also increased due to which quality of the train is decreased.
When this train had rsa with Narayandri exp, that time it was the best train because CDO was tirupati and maintenance was also best but now...
more... this train is running at its worst, 12703 is average but 12704 is even bad.
My recommendation, this train should be controlled under SER-Santragachi because its maintenance time is very less in SC. And if possible take any weekly superfast train like 12773, 22849 for even better experience. If anyone doesn't relate with my opinion please feel free to reply.
