It began as a freight line for mines and other industries to service the mountain towns of Wales during the 1860's, but eventually became both a freight and passenger line during the 1880's, and eventually ceased full operation during the 1940's, but eventually grew into a tourist railway with locomotives from other railways being added into service, as well as building their own unique types of diesel locomotives.
None of the locomotives have been fully retired, nor has the railway ever closed. Hence, the railway being famous for operating some of the oldest and smallest steam locomotives to have never been fully retired.
What's also unique about the railway, is the fact that they name locomotives and rolling stock rather than numbering them; yet they began numbering once the railway grew. They also have locomotives preserved on static display in their narrow-gauge museum.
