The Bandon Tanks excelled due to their elegant design, high power output and compact wheel arrangement, which suited the track of the CB&SCR network.
Introduction and CB&SCR service
The 4–6–0T wheel arrangement was more typically found on narrow gauge lines, because the restricted bunker space (and resultant limited coal capacity) is less of a hindrance on the typically shorter journeys of such lines. A
4-6-2T wheel arrangement would have given more bunker space, but it would have been too long for the CB&SCR's turntables. The
wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front ...
was also short-coupled (close to each other) in order to manage the tight curves on the CB&SCR lines. Each locomotive had capacity for two tons of coal and 1,100 gallons of water and weighed 56 tons 10 hundredweight.
The first member of the class was 11 which was ordered in 1905, cost £3,145 and was delivered in June 1906.
The next to be built was 14, which was ordered in 1908, cost £2,575 and was delivered in March 1909.
[ These were followed by 15 in October 1910, 20 in July 1912 and 19 in June 1914.][

restrictions prevented Beyer, Peacock from completing and delivering it until October 1919.[ The two final members of the class were 8 and 13, which were delivered in November 1920.][
Operationally the Bandon Tanks were small and powerful locomotives, well regarded apart from the cramped cab and the difficulty of cab access due to the rear wheel splashers. Despite the bunker size being limited by the 4–6–0T layout, Bandon Tanks had no difficulty covering distances on the CB&SCR network, the greatest of which was between and ]Baltimore

GSR and CIÉ service and withdrawal
The GSR renumbered the class 463 – 470 and later designated it Class B4. Between 1935 and 1947 the GSR rebuilt five of the class with type "R" Belpaire superheated boilers.
The majority of the class continued to work on the former CB&SC network, but in 1929 the GSR transferred 468 to Grand Canal Street depot in Dublin for suburban service on the former Dublin & South Eastern Railway main line between Dublin Westland Row and . In 1939 first 470 and then 466 were also transferred to Grand Canal Street. 469 replaced 466 on the Bray line for just over a year, from 1941 until 1942. 466 became the last Bandon Tank in service on the Bray line, remaining there until September 1956.
465 and 469 were withdrawn in 1945.[ CIÉ withdrew 467 in 1959.][ CIÉ withdrew 466, 468 and 470 in 1961,][ the year that it closed the former CB&SCR network. 463 and 464 stayed in service until 1963,][ which was CIÉ's final year of steam traction.

Livery
In CB&SCR service the class was painted olive green with yellow lining. Throughout the period of Great Southern Railways operation (1925-45), along with all locomotives on the West Cork system (and further afield), they were all-over unlined dark grey, which was carried over into CIE days. In CIÉ service there was some variation in liveries.
*466 was painted lined CIÉ green in December 1948.
*467 was a dark blue-green in 1953.
*470 was a dark matt off-black (likely to be a local variation of the standard dark grey livery) in 1954 and 463 was the same in 1962.
*464 appeared to be gloss black in 1961.
Any others remained dark grey.
