Revenue stamps of Northern Ireland
Upon the partition of Ireland in 1921, separate revenue stamps began to be issued for both Northern Ireland and Southern Ireland. The latter were withdrawn soon afterwards upon the establishment of the Provisional Government, but the former continued to issue revenue stamps until the late 20th century. The need for separate issues for Northern Ireland came about since taxes raised there were meant to remain in the country. Most Northern Irish revenue stamps were British key types with appropriate inscriptions, but there were a number of different issues as well.
Steam locomotives of Ireland
The West Donegal Railway became the Donegal Railway in 1892; and the County Donegal Railways Joint Committee after being jointly acquired in 1906 by the Great Northern Railway (Ireland) and the Midland Railway's Northern Counties Committee.
The Great Northern Railway (Ireland) straddled the border between the Republic and Northern Ireland (after 1921), and so was not incorporated in either the CIÉ or UTA. However, mounting losses saw the network purchased jointly by the Irish and British governments on 1 September 1953. It was run as a joint board, independent of the CIÉ and UTA, until 30 September 1958 when it was dissolved and the remaining stock split equally between the two railways.
