The only train in Laos
To continue our theme of catching a train in every country (which I just realised we have failed on as we were in NZ for so long that we forgot to do it before we left). The French built a railway line from one end of Don Khon to Don Det which seemed very odd given that they are very small islands until we read that it was to transport cargo which had come by boat and could go no further because of a rather large waterfall which Don Khon is at the bottom of and Don Det is at the top of. Awhawheehaw.
