Great Southern and Western Railway class 99 0-6-0T loco
No 90 was built for the Castleisland Railway in 1875 as an 0-6-4 with attached carriage section. Originally numbered C, on becoming GSWR property in 1879, it was renumbered 90.
In 1915 no 90 was rebuilt as an 0-6-0T without carriage section, and in GSR days allocated to Cork Albert Quay along with similar loco no 100.
Withdrawn in 1959, it is now preserved.
2 more locos were built without a carriage section in 1890-1 for use on the Fermoy to Mitchelstown branch. Numbered 99 and 100, There were a few differences. No 99 was scrapped in 1930, but no 100 survived till 1959, working with no 90 at Cork.
Requires finishing off, wheels and mechanism etc.
