The Great Southern and Western Railway Class 90 is a class of 0-6-0T steam locomotive. They were one of the smallest steam locomotives to be inherited by the CIÉ on its formation.
History
In 1875 Inchicore Works outshopped two railmotors, steam locomotives with a carriage on the same chassis to work the Castleisland and Gortatlea Light Railway. Both railmotors were rebuilt (the first in 1890) removing the carriage portion and leaving the locomotive as a small and light 0-6-0T. The two examples were numbered 90 and 100 and were put to work in the Cork area. Unusually, the centre driving wheels were flangeless giving very good working over tight radius tracks. They regularly shunted along the quayside at Cork and worked the car trains from the Ford works to Rocksavage yard. In the summer months both locomotives were coupled together to work the excursion trains on the lightly laid Timoleague and Courtmacsherry Light Railway.
In 1890 the class was enlarged with Inchicore building two further examples for use on the Fermoy to Mitchelstown branch and two for the Kingsbridge to Inchicore branch, which they worked until 1945. Several detail changes were made over the years. One of the most noticeable was the replacement of the original chimney (which had a pronounced taper from base to apex), being replaced with a parallel version with a distinct lip.
Dimensions
- Driving Wheels: 3 ft 8 1⁄2 in (1.130 m) (10 spokes), centre wheels flangeless.
- Cylinders: (2) 12 in × 18 in (305 mm × 457 mm)
- Boiler Pressure: 150 psi (1.03 MPa)
- Weight: 22 long tons 9 cwt (50,300 lb or 22.8 t)
Livery
As locomotives they were painted in green with black and white lining, numbers were large, yellow, shaded white and blue. Under the Córas Iompair Éireann (CIÉ) they were painted black with large yellow numbers on the tank side.
Preservation
One example, No. 90, was preserved for many years as a static exhibit at Mallow. This was painted in the green livery, as detailed above, but a cast number plate with black numerals on a silver background (not original) has replaced the painted numbers. After a brief spell in the CIÉ workshops at Inchicore No. 90 was removed to the workshops of the Railway Preservation Society of Ireland at Whitehead in 2005, to undergo restoration. The locomotive was back in steam by November 2006 and can now be seen working at the Downpatrick Railway Museum.
