About
The Welsh Highland Heritage Railway at Porthmadog is a dedicated preservation railway and museum operating from the site of Gelert's Farm Works, safeguarding the history and rolling stock of the original Welsh Highland Railway — one of the most celebrated and romantic of all Welsh narrow-gauge railways. Operating on the 597mm (1 foot 11½ inch) gauge pioneered by the pioneering narrow-gauge railways of Snowdonia, the heritage railway preserves a slice of railway history intimately connected with the industrial and transport landscape of North Wales.
The original Welsh Highland Railway was assembled from several earlier lines — the Croesor Tramway, the North Wales Narrow Gauge Railways and connecting sections — to create a through route from Porthmadog to Caernarfon, a distance of approximately 22 miles through the dramatic mountain scenery of Snowdonia. After years of financial struggle the full route opened in 1923 under the management of the Festiniog Railway, but passenger numbers were never sufficient to make the line financially viable. The railway closed in stages between 1933 and 1937, leaving behind a remarkable collection of locomotives and rolling stock that were subsequently preserved by enthusiasts.
The Welsh Highland Heritage Railway preserves and operates a section of the original route at Porthmadog, running from the Gelert's Farm site through a short length of original trackbed. The site also houses the locomotive shed and workshop where a remarkable collection of preserved narrow-gauge locomotives and rolling stock is maintained. The museum aspect of the operation displays historical artefacts, photographs, documents and smaller items associated with the Welsh Highland and its predecessor lines, providing essential context for understanding this fascinating corner of Welsh railway history.
The site operates alongside but independently from the Ffestiniog and Welsh Highland Railway, which separately restored the full Caernarfon to Porthmadog route from 1997 onwards, reopening the complete line in 2011. The two operations complement each other, with the Heritage Railway focusing specifically on the preservation of original Welsh Highland Railway artefacts and the educational interpretation of the line's history from its 19th-century origins to its 1937 closure.

💡 Visitor Tips

- Combine your visit with the Ffestiniog and Welsh Highland Railway (operating from Porthmadog Harbour station) for a comprehensive narrow-gauge railway experience.
- The railway enthusiast gift shop stocks a good range of books, DVDs and models relating to Welsh narrow-gauge railways.
- Portmeirion, the famous Italian-style village designed by Clough Williams-Ellis, is just 3 miles away — ideal for a combined day out.
- The Snowdonia setting means weather can change quickly — bring a waterproof jacket.
- Photography enthusiasts should check for special photographic charter events when unprecedented access to locomotives may be available.
- The café provides refreshments and a welcome stop during your visit.
- Allow 1–2 hours for the museum site visit, and longer on steam event days.
