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 in this class was also built by Peckett and Sons and delivered to the railway in 1914. This locomotive was numbered "No. 3" and originally named "Consiliation" but later renamed "Kent". This replaced the original No. 3, named "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 No. 1S was withdrawn and scrapped in 1936; but No.3S survived until nationalisation when it passed to Córas Iompair Éireann. Eventually, it was withdrawn and scrapped in 1953.
