Irish North Western Railway (INW) was an Irish gauge (5 ft 3 in (1,600 mm)) railway company in Ireland.
The company was founded as the Dundalk and Enniskillen Railway (D&ER) and opened the first section of its line, from Dundalk Quay Street to Castleblayney, in 1849.[1][2] In Dundalk the D&ER line crossed the Dublin and Belfast Junction Railway main line, which was completed between Drogheda and its own separate Dundalk station in the same year.
The D&ER extended westwards, reaching Ballybay in 1854,[2] Newbliss in 1855[2] and Lisbellaw in 1858.[3] In 1859 the D&ER reached Enniskillen where it connected with the Londonderry and Enniskillen Railway (L&ER).[3] The L&ER had been completed in 1854[3] but had been unprofitable, so in 1860 it leased its line in perpetuity to the D&ER.[4] This gave the D&ER a direct route between Dundalk and Londonderry Foyle Road.
In 1862 the INW opened a branch from Clones southwards to Cavan.[5] In the same year the company renamed itself the Irish North Western Railway.[6] In 1863 the Ulster Railway reached Clones where it made a junction with the INW.[7] In 1868 the Enniskillen and Bundoran Railway opened between Bundoran Junction and Bundoran,[3][8] and contracted the INW to operate its line.[6]
In 1876 the INW merged with the Northern Railway of Ireland and the Ulster Railway to form the Great Northern Railway.[6]
The GNR operated the line between Dundalk and Enniskillen until 1957, when the Government of Northern Ireland made the GNR Board close all cross-border lines except the Dublin and Belfast Junction Railway mainline.[9][10] Córas Iompair Éireann continued a freight service between Dundalk and Clones for a few years, but withdrew this and closed the line in 1960.[10]
