The Festiniog Railway Heritage Group plays a vital role in preserving the legacy of the world's oldest narrow gauge railway, located in Wales. Established after World War II to safeguard the railway's historical significance, the group has become the conscience of the Festiniog Railway, advocating for the preservation and celebration of its rich heritage.

Each year, thousands of visitors embark on scenic journeys from Porthmadog to Blaenau Ffestiniog, experiencing the unique charm of steam engines and breathtaking views of Snowdonia. The heritage group actively supports ongoing restoration projects and organizes events, such as the popular Victorian Weekend, which highlights the railway's storied past.

Members receive a quarterly journal that details the group’s activities and historical insights, contributing to fundraising efforts for future projects. With an extensive archive and a treasure trove of locomotives and artefacts, the Festiniog Railway Heritage Group is committed to ensuring that this historical gem continues to inspire and educate future generations.
