Dublin, Wicklow and Wexford Railway (DW&WR) 15 of 1860 was the first of a number of 0-4-2 tender locomotives built by Sharp Stewart who were the only supplier of the 0-4-2 type to the DW&WR.
In practice the DW&WR mostly employed the locomotives with the higher tractive effort on main line freight and the others on mixed passenger/freight trains.
At least three were damaged beyond economic repair during the Irish Civil War, although there may be some claims some were simply life-expired.
When the Dublin and South Eastern Railway (DSER)[Note 2] Upon grouping into the Great Southern Railways most DSER were inspected or considered at Inchicore.
The resulting immediate cull of over twenty of the DSER's 67 locomotives included all remaining six or seven remaining 0-4-2 engines including the Civil War losses.
