The history of rail transport in Ireland began only a decade later than that of Great Britain. By its peak in 1920, Ireland had 3,500 route miles (5,630 km). The current status is less than half that amount, with a large unserviced area around the border area between Northern Ireland and The Republic of Ireland.

The Western Railway Corridor is a term, used since c. 2003, for a partly disused railway line running through the west of Ireland.

The Great Southern and Western Railway (GS&WR) was an Irish gauge railway company in Ireland from 1844 until 1924. The GS&WR grew by building lines and making a series of takeovers, until in the late 19th and early 20th centuries it was the largest of Ireland's "Big Four" railway networks.

The MGWR Class D-bogie were first 4-4-0 operated by the Midland Great Western Railway (MGWR) of Ireland. They were rebuilt from MGWR Class D 2-4-0 locomotives in 1900/01 with the intention to use them on the Dublin to Sligo mainline but they proved underpowered for this work and were allocated to more suitable work around County Mayo, including Achill. This led to their nicknames of Mayo Bogies or Achill Bogies. Following the merger of the MGWR into Great Southern Railways (GSR) they also became designated class 530 or D16.
