The railway track gauge is 1 foot 11 3/4 inches, historically known as the 'fictitious gauge' used in Welsh slate transport.
The locomotives were built by the Hunslet Engine Company in Leeds between 1895 and 1910.
The line traverses the Bala Lake shoreline, which is home to the gwyniad, a rare relic fish species from the Ice Age.
The original GWR trackbed was closed to standard-gauge traffic in 1965 before being repurposed for this heritage project.
The railway serves as a crucial transport link for hikers accessing the Arenig and Aran mountain ranges.
Bala Lake Railway is a narrow-gauge heritage line running on the trackbed of the former Great Western Railway Ruabon to Barmouth line. The 4.5-mile journey takes passengers along the southern shore of Llyn Tegid, the largest natural lake in Wales. The railway operates using a collection of historic steam locomotives, including 'Alice' and 'Holy War,' originally built for Welsh slate quarries. Each train offers open-carriage seating providing unobstructed views of the Eryri (Snowdonia) National Park landscape. The line terminates at Llanuwchllyn, where visitors can view the engine shed and maintenance facilities. The railway is a significant contributor to the preservation of local industrial rail heritage.

Do not attempt to walk along the tracks outside of designated station areas; do not expect a high-speed transit experience.
