On a recent trip to Sabah, in Malaysian Borneo, I learned of a nineteenth-century train line that’s still in operation. Starting from Kota Kinabalu, the biggest city in Sabah, the train takes you along the coast to the small town of Beaufort. From there, you can take a second train that roughly traces the Sungai Padas River to the coffee-producing town of Tenom. I love traveling on old trains, so this adventure seemed right up my alley. But it was not without its roadblocks (or landslides).
