Heritage railways
Wales has a large number of heritage railways. Some of these were former industrial narrow gauge railways, such as the Corris Railway. Others were formed from portions disused standard gauge railways, either kept as standard gauge (e.g. Barry Island Railway) or converted to narrow gauge (e.g. Brecon Mountain Railway). Some of the narrow gauge heritage railways are marketed as the Great Little Trains of Wales.
Notable heritage railways include:
- The Talyllyn Railway, the first railway in the world to be saved by a preservation society
- The Snowdon Mountain Railway, the only rack and pinion railway in the United Kingdom
- The Ffestiniog Railway, the oldest surviving railway company in the world
- The Vale of Rheidol Railway, the last steam railway owned by British Rail until 1989
