The aim of The Trust is to record and interpret the history of narrow gauge railways in the British Isles and beyond. While a number of passenger carrying railways have been preserved and continue to operate, primarily now to satisfy the tourist market, many other passenger carrying lines, as well as numerous industrial and military ones, ceased to exist in the mid 20th century. Thanks to the pioneering enthusiasts and collectors of those times, our collection enables us to tell the story of these railways, most of which never achieved the widespread following enjoyed by their main line neighbours.
