Inchicore, west of Dublin's city centre, is the principal locomotive and carriage works of Irish Rail, where locomotives, diesel railcars and rolling stock are maintained. Built by the Great Southern & Western Railway in 1846 with the opening of their mainline from Dublin to Carlow, Inchicore is the largest single industrial complex in Ireland, and includes one of the last remaining active locomotive sheds on Irish Rail, as well as a turntable. For over a 150 years, Inchicore has witnessed the building, assembly and maintenance of many generations of steam and diesel motive power. With the setting up of the Great Southern Railways in 1925, and later CIE's formation in 1945, the works became the principal location for the overhaul of rolling stock, while other smaller workshops around the country were run down and closed altogether.
Today, Inchicore still plays a role in the maintenance of Irish Rails locomotive fleet, mainly the 071 and 201 Class locomotives, along with the railcars and DART units, although these latter two have also been gradually maintained at other modern Irish Rail depots such as those at Portlaoise and Drogheda.
