The Great Southern Railways Class 800 steam locomotives were built principally for express passenger work on the Dublin to Cork main line of that company. These locomotives were designed under the supervision of E. C. Bredin with his Chief Draughtsman, H. J. A. Beaumont, preparing the drawings. They were the largest and most powerful engines ever to run in Ireland by quite a large margin, and the only three express passenger locomotives to be built in an independent Ireland.[1]
Design
The engines had three Шаблон:Convert cylinders and Шаблон:Convert boiler pressure. The nominal tractive effort was Шаблон:Convert, which corresponded with Great British main-line power. Further, it was the only design which exploited the full extent of the extra width afforded by the Шаблон:Convert gauge. Originally four or five were to be built, named Maeḋḃ,[2] Maċa, Táilte, Gráinne, and Deirdre, but only three were eventually produced - 800 Maeḋḃ in 1939, with Maċa (801) and Táilte (802) in 1940, along with a fourth boiler which acted as a spare. They were intended for the Dublin–Cork route, but wartime coal shortages and the early 1950s advent of diesels on main line services resulted in their never having had much chance to show what they were capable of. In the 1950s, they gradually became neglected and even resorted to light goods trains on occasion, with little other work to do.Шаблон:Citation needed

| 800 | 1939 | [[Medb|Шаблон:Gaelic]] | Maeve or Maedhbh | 1962 | Preserved |

The name and number plates were of cast bronze with polished raised lettering and beading on a blue painted background. The nameplates’ lettering was in Gaelic script using dot above in place of the 'h' (see Irish orthography), although at first locomotive 800 was planned to carry an Anglicised name Maeve in Roman type, though it never did.Шаблон:Citation needed
No. 800 Maeḋḃ was withdrawn from service in 1962 and is now on display at the Ulster Folk and Transport Museum, Cultra, County Down.Шаблон:Citation needed
Livery
The engines were turned out in a unique livery, which no other locomotives ever carried. In the height of the Great Southern era, when every single locomotive in Ireland was painted in plain unlined battleship grey livery, these engines were turned out in a smart mid-green, with a distinct bluish tint. The green was lined in black and light yellow, and the GSR coat of arms was carried on the tender, flanked by large pale yellow letters "G S", which appear to have been shaded in red and gold. The cabside number plates and nameplates had blue backgrounds, and raised polished brass rims and numerals.
In Córas Iompair Éireann days, they received the 1950s standard green, somewhat darker than they had carried before, with black and white lining. In the early 1950s, Táilte was apparently repainted a light green, as an experiment. The colour was not unlike the green used for coaches on CIÉ in the late 1950s, but she was then repainted like her sisters. Maċa and Táilte's nameplates and cab side number plates were given red backgrounds in the mid-1950s instead of the dark blue that they had originally, however Maeḋḃ retained the blue background. This is the livery the preserved 800 carries, though rather than the CIÉ "flying snail" emblem which would be appropriate to this later livery, it incorrectly carries the earlier "G S" without shading, and a replaced GSR coat of arms.
Service
Шаблон:Original research section The locos entered service between 1939 and 1940.[3]Шаблон:Rp Their axle load was 21 tons[3]Шаблон:Rp which meant that they could only work on the Dublin-Cork mainline.Шаблон:Citation needed They were noted for climbing the steeply graded route from Cork Kent station (then Glanmire road station) unassisted, but because of coal shortages after WWII[3]Шаблон:Rp they never got a chance to show their full potential.Шаблон:Citation needed They were slightly modified in the early 1950s with Maċa and Táilte receiving single funnels[3]Шаблон:Rp and all three gaining extra hand-railings and a wheel on the smoke-box door instead of a dart.Шаблон:Citation needed The main difference following these modifications was a decrease in tractive effort.[3]Шаблон:Rp
With the arrival of the Metropolitan-Vickers A class first generation diesel locomotives in the 1950s, they were made virtually redundant, with Táilte being taken out of service in 1955 and scrapped two years later.[3]Шаблон:Rp However, Maeḋḃ and Maċa remained in service pulling light expresses and goods trains.[3]Шаблон:Rp Maeḋḃ was taken out of service in 1962 and was repainted at Inchicore for preservation. Both Nos. 800 and 801 were noted for being at Thurles in the 1960s after withdrawal.Шаблон:Citation needed Maċa was retubed for an IRRS tour in 1964 and was steamed up for the last time,Шаблон:Citation needed after which she was scrapped. Having been at Thurles for a year 800 was brought to the Belfast Museum.Шаблон:Citation needed In 1993, Maeḋḃ, along with the NCC compound Dunluce Castle and the GNR S class 4-4-0 No. 171 Slieve Gullion were brought to the new Ulster Folk and Transport Museum, Cultra.Шаблон:Citation needed

An etched-brass 4 mm scale model is available from Studio Scale Models.[4] There is a detailed O Gauge model of engine 800 in the Fry model railway collection.[3]Шаблон:Rp
