The Irish railway system commenced in 1834 with the Dublin to Kingstown line. Between the Great Famine and the Great War the network steadily grew. The network peaked in 1914, when 1,137 stations were operating, and declined markedly in the latter half of the 20th century. By the turn of the millennium, only 250 stations were in operation across the island. This interactive map charts the rise and fall of Ireland’s railway network by digitizing “Johnson’s Atlas & Gazetteer of the Railways of Ireland” (Johnson, 1997). The data displayed here was used to inform the work of Fernihough and Lyons: “Agglomeration and Emigration: The Economic Impact of Railways in Post-Famine Ireland” .
