Nos. 1, 6, 7 and 10 built between 1892 and 1896 had detail differences,[2] Ahrons describes them as having a more modern appearance.[3]: 48
Locomotive No. 10(St. Seneanus) was 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.[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On review following amalgamation into Great Southern Railways (GSR) in 1925 Nos. 1, 2 and 6 were promptly withdrawn despite No. 2 having received a new boiler in 1914.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 Unlike the other survivors No. 426 had not been re-boilered in 1914–1916 and it was withdrawn in 1926.[2]
