This delightful set of photos popped up on my Facebook feed.  All in Mandarin, so I am totally unsure of ownership, but nothing on the post.  Just a wonderful set of narrow gauge pictures.  Looks like an ore or coal carrying line, pictured in the wet, monsoon, season.  And some interesting push-cart lines for passenger services.

Makes you wonder about the hidden gems of railways tucked away in the less (to us) well-known parts of the world.  You’d need a whole new set of scenic techniques to model tropical vegetation and monsoon weather.
