Dublin, Wicklow and Wexford Railway (DW&WR) 55 to 58 were 4-4-0 locomotives built from 1895 at Vulcan Foundry for express passenger duties on the Dublin—Wexford mainline. They were to remain the DW&WR's and subsequent Dublin and South Eastern Railway's leading express passenger locomotive until the arrival of Nos. 67 and 68 some ten years later.
