Diesel locomotives of Ireland
A wide variety of diesel locomotives have been used on Ireland's railways. This page lists all those that have been used in the Republic of Ireland and Northern Ireland.
Republic of Ireland
Initially, Córas Iompair Éireann (CIE) numbered and classified its handful of early diesel locomotives in the same number series as its steam locomotives. However, it soon developed a series based on a series of Types according to engine power, with the highest-powered locomotives being Type A and numbered in the A0xx series, and the lowest powered being Type G and numbered in the G6xx series. Locomotive K801 was a one-off prototype locomotive and did not truly fit in this scheme.
Since all the locomotives were in fact numbered in series, the letter prefix to the number was later dropped (in 1972), as was the allocation of numbers according to power. The low-powered locomotives that were rebuilt with higher-powered engines were not renumbered, and newly built locomotives have simply taken the next available number series.
