The idea was to link the commercial coal, bauxite, iron, limestone, lignite and basalt industries along the north coast with the commercial harbour of Portrush. The ambitious proposal failed due to a lack of finance and doubts about returns, a narrow-gauge railway though was built from Ballycastle to Ballymoney via Armoy and Dervock. The Giant's Causeway tramway came about by the vision and enthusiasm of Col. William Traill and his brother Anthony of Ballylough, William was an advocator of the railway and kept well informed on technological development including the work of Seimens whose system provided the transmission for the tram. A power station was built at the Walkmill Falls with vertical water turbines to generate the electric power.
