The Snowdon Mountain Railway is unique in Britain, being the only public rack railway. It runs from Llanberis to 20 feet below the summit of Mount Snowdon, the highest peak in Wales.
Opened in 1896, it uses the Abt rack system developed in Switzerland to allow the one-carriage trains to ascend nearly 3,000ft in a little over 4 miles. Although it now has a fleet of diesel locomotives and railcars, many services are still steam operated using locomotives dating back to the 1890's.
The ride up Snowdon gives spectacular views and glorious sound effects as the locomotives work hard pushing your carriage up the mountain - weather permiting of course.
