Ffestiniog Railway

The Ffestiniog Railway is one of the most important railways in the world — not simply in Wales, not simply in Britain, but in the world. Built in 1836 to carry slate from the quarries of Blaenau Ffestiniog to the port at Porthmadog, it became the first narrow-gauge railway in the world to carry passengers using steam locomotives, and later became a pioneering model for railway preservation that inspired dozens of heritage lines across Britain and beyond.

Today the railway operates along 21 kilometres of track between Porthmadog on the coast and Blaenau Ffestiniog in the mountains, climbing 213 metres through scenery that encompasses estuary, forest, moorland and the dramatic slate landscape of Blaenau. The journey takes approximately an hour in each direction and is one of the finest train rides in Britain.

Key Facts

The Journey

From Porthmadog the train crosses the Cob — a kilometre-long embankment across the Glaslyn estuary — with views of the mountains rising ahead. The line climbs steadily through the Afon Glaslyn valley, passes Tan-y-Bwlch station (once a fashionable resort for Victorian tourists), and enters increasingly dramatic terrain as it approaches Blaenau. The famous Deviation — a section of new track built by volunteers in the 1970s to bypass a flooded section — demonstrates the remarkable engineering that has kept this railway alive.

Preservation Story

The Ffestiniog closed to passengers in 1946 following wartime damage and financial difficulties. A small group of volunteers began restoration in 1954 — an act of collective determination that required rebuilding the entire infrastructure from scratch. The railway reopened progressively through the 1950s and 60s and reached Blaenau in 1982. The Ffestiniog's preservation inspired the Talyllyn (the world's first preserved railway) and dozens of subsequent projects. Modern railway preservation as a concept owes a significant debt to those early volunteers.

Combining with Other Railways

The Ffestiniog connects at Porthmadog with the Welsh Highland Railway, which runs north through Beddgelert and on to Caernarfon. A combined journey on both lines — the Porthmadog–Caernarfon route — makes for an exceptional full-day rail experience through the heart of Eryri.
