The terrain is not a problem. Only problem is naxalite, whom our Govt have already "very aggressively slapped" by starting train for Dalli rajhaara - Gudem (which is heart of naxalite).
And regarding araku valley, ECoR were already planning to increase passenger train service on this route (a special Kirandul-vskp was even started).
