Details refer to class 47

The Great Southern and Western Railway (GS&WR) Class 47 consisted of twenty 0-4-4BT locomotives designed by Alexander McDonnell and introduced from 1883. They were intended for branch lines around Cork and for Dublin—Kildare and Dublin-Kilkenny services.

Class 47 was preceded by four members of class 28 introduced from about 1879, these having a slightly longer wheelbase. Only one of class 28 remaining into GSR service when it was renumbered 40 and included in GSR Class 47. This was the 100th locomotive built under the Alexander McDonnell period and was temporarily numbered 100 when new.
