The '''[[Dublin, Wicklow and Wexford Railway]] (DW&WR) 2''', built in 1885, was the predecessor to a total of eleven {{whyte|2-4-0|T}} locomotives to emerge from [[Grand Canal Street railway works]] between 1885 and 1896.<ref name="JCMM-DSER-2"/>
Nos. 1, 6, 7 and 10, built between 1892 and 1896, had detail differences between them,<ref name="JCMM-DSER-2"/> Ahrons describes them as having ''a more modern appearance''.<ref name="AV6"/>{{rp|48}}
Locomotive No. 10 (''St. Seneanus'') was [[DWWR 11|rebuilt as 2-4-2T]] in 1903. Nos. 28 (''St. Lawrence''), 45 (''St. Kieran''), and 46 (''Princess Mary'') were also rebuilt later in 1909/10.<ref name="JCMM-DSER-2"/>
On review following amalgamation into [[Great Southern Railways]] (GSR) in 1925, Nos. 1, 2 and 6 were promptly withdrawn despite No. 2 having received a new boiler in 1914. The remaining four engines Nos. 7, 9, 47 and 49 were designated GSR class 423/G1 and allocated the numbers 426, 424, 425 and 423 respectively. Unlike the other survivors, No. 426 had not been re-boilered in 1914–1916 and it was withdrawn in 1926.<ref name="JCMM-DSER-2"/>
