Yes Mr Anish , Visakhapatnam-Borra Caves-Araku-Koraput-Jagdalpur-Dantewada-NMDC Kirandul is superb hit for sightseeing as well as transportation of world's best high density iron ore from NMDC Bailadilla Mines. Now Vistadome Coach is also attached to Kirandul Passenger for journey b/w Vizag znd Araku. Sightseeing views are at its best along this line of tunnels and hills. Now generally three WAG 9 are provided to wagons of iron ore. An overnight express train b/w Visakhapatnam and Jagdalpur is also introduced last year and this year's IRTTC mentioned the extension of Vizag-Rayagada-Koraput pass to Jagdalpur. This Passenger also give spectacular views of tunnels and hills between Rayagada and Koraput corridor of NALCO. Both these lines give lifetime spectacular sightseeing views.
