John talks with Professor Dafydd Fell of SOAS University about "The Twilight Years of Taiwan’s Sugar Railways", his new book co-written with Wang Xiang, a researcher who has spent years documenting the remains and memories of this once vast railway network. Fell’s own fascination with the sugar railways dates back to the 1990s when he was living in Taiwan. John and Dafydd explore how sugar helped build modern Taiwan, how the narrow-gauge railways moved far more than just sugar cane, and how the network had a Cold War strategic purpose. The episode is full of nuggets, from mystery Belgian locomotives to propaganda train tours.
