Oernant Tramway refers to a horse-drawn tramway which connected slate quarries located to the North-West of Llangollen with the Pentrefelin canal wharves at Llantysilio. It is simply referred to as "the tramway" in contemporary publications and appears to have been entirely owned by the Llangollen Slate and Slab Company. The tramway was built in the 1850s, reaching a maximum length approaching seven miles by 1857, and was used until about 1892. It had gravity-worked inclines, and was horse drawn on the level sections.
