History

edit

The first member of this class was numbered "No. 1" and named "Gabriel", replacing the original No. 1, named "Marion", which was scrapped on its arrival.

The second locomotive was also built by Peckett and Sons and delivered to the railway in 1914. It was numbered "No. 3" and originally named "Consiliation" but later renamed "Kent". This replaced the original No. 3 "Ilen", which was scrapped when the new locomotive arrived.

Both locomotives passed to the Great Southern Railways in the 1925 amalgamation. The GSR added an "S" suffix to the running number and classified both locomotives as Class 1S (or Class DN4). No. 1S was withdrawn and scrapped in 1936, but No. 3S survived until nationalisation when it passed to Córas Iompair Éireann. Eventually, it was withdrawn and scrapped in 1953.

The S&S pair were two of a class of five engines, two others went to Borneo and scrapped c. 1947, whilst the last is currently preserved on the Bay of Islands Vintage Railway in New Zealand.[1]
