There are three heritage railways in Northern Ireland, reflecting Ireland's long railway history. These are:
The Downpatrick and County Down Railway in County Down is located on part of the former Belfast & County Down Railway. Two and a half miles track has been relaid to Inch Abbey on the old route to Belfast, and a further one mile laid along the old route to Newcastle. It operates with preserved steam and diesel locomotives and vintage wooden carriages. The Foyle Valley Railway, in County Londonderry. The project has faced some difficulties, but does hold a quantity of preserved railway stock, on part of one of Derry city's closed railway routes (the city once had four stations). The Giant's Causeway and Bushmills Railway on the north coast in County Antrim. Steam-powered services run from the Giant's Causeway to Bushmills. Laid on part of the course of the original Giant's Causeway Tramway which was electric-powered, with its own hydroelectric plant – the first such system in the world.
