My brother and sister walked 325km from Ban Pong to Sangkhla Buri along what exists of this very railway. It was in memory of a POW my brother met at our church who worked on the railway during his time in the war.

My sister wrote a book about the experience called Norn Lup? A Journey Of Railways, Roads, & Wats. http://intrepid-girl.com/blog/writing/buy-the-book-norn-lup-...

And my brother made a documentary http://www.lukenowell.com/projects/lukenowell/thailandtrek/

Hope people don't mind these plugs but they both add value to the story behind this railway and the people who worked on it against their will.
