The Dolgoch is an 0-4-0T narrow-gauge steam locomotive built in 1866 for the Talyllyn Railway. Designed for steep gradients and tight curves, it features four coupled driving wheels and a saddle-tank layout that provides good adhesion on light track. Known for its historic significance, remarkable longevity, and reliable performance, Dolgoch became iconic for hauling passenger trains on one of the world’s oldest preserved railways.
