One thing needs to understand is.. These are not thick/dense forest.. Polavaram and this rail route are two different directions and two different things.. Most important thing is Railways/governament can develop forests much on the near by areas while lying this route..
Most importantly it will reduce distance between SC/KZJ to VSKP/HWH. acts as a 2nd route in that area and removes congestion/loco reverse problem in BZA. It will give needed connectivity for tribal and industrail areas of khammam and godavari distrcits, which is lesser known to world..
Another thing is while having...
more... a highway through that route, why cann't a railway route be made, As this helps a lot to eco system than a highway..
