The Ffestiniog Railway was the first narrow-gauge railway in the world to introduce steam locomotives in 1863.
The railway climbs over 700 feet from sea level to the mountain town of Blaenau Ffestiniog.
It utilizes the world's first Fairlie articulated steam locomotives, designed to negotiate tight curves.
The line crosses the Cob, a mile-long embankment that reclaimed land from the Glaslyn estuary.
The railway operates its own engineering works where historic engines are maintained and rebuilt.
The Welsh Highland Railway extension was completed in 2011, reconnecting the historic route to Caernarfon.
Some carriages feature open-air observation cars, specifically designed to capture the landscape.
The gauge of the track is 1 foot 11.5 inches (597 mm), classified as 'narrow gauge'.
The Ffestiniog & Welsh Highland Railways operate the world's oldest independent railway company, established by an 1832 Act of Parliament. The network spans 40 miles of track through the Snowdonia National Park, utilizing both vintage steam and diesel locomotives. The Ffestiniog line was originally constructed to transport slate from Blaenau Ffestiniog to the Porthmadog harbor for export. The Welsh Highland line connects Caernarfon to Porthmadog, forming the longest heritage railway in the United Kingdom. Operations are based at Harbour Station, which serves as the primary hub for both lines. The rolling stock includes restored historic carriages, some of which date back to the 19th century. Passengers travel through varied landscapes including mountain passes, coastal marshes, and dense forests. The railway is managed by the Ffestiniog Railway Society and relies on a mix of professional staff and volunteers.

Book tickets in advance as specific carriages, particularly the observation cars, sell out quickly.
Carry a light windbreaker or waterproof jacket, as mountain weather in Snowdonia changes rapidly.
Choose a seat on the left side of the train when traveling from Porthmadog to Blaenau Ffestiniog for the best views of the valley.
Do not attempt to board trains without a pre-booked seat, as they often run at full capacity.
Reduced service frequency during winter months; specific lines may close for maintenance in late autumn.
