I never go to see
Where it ends.
It fills a few hollows,
And makes banks for the swallows,
It sets the sand a-blowing,
And the blackberries a-growing.
-- Henry David Thoreau
I was once travelling between Haridwar and Rishikesh, when I came upon this railroad. It later struck me as rather odd that this, in the middle of nowhere, was the most beautiful sight I saw in that trip.
So in case you find yourself travelling between H and R by road, and you see a flash of steel among the breaks in the woods that flank the road, I strongly urge you to stop, walk down to the railway tracks, and - as Mr.Davies puts it - stand and stare.
And while you do, try not to catch the train to Dehra-Dun in the small of your back.
