And what of the tunnel to the right in the photo?

@white.dead That is space for the water to flow...it is canal like structure which goes under the track

@jmadhavadas
Very unusual and interesting place. What is it? Some national Park? Where exactly is it?

@white.dead This is Western Ghats , thick mountainous forest

Great!
