Data from "Four-coupled Passenger Engines, Ulster Ry", Locomotive Magazine, Volume XXV [25] (15 August 1919), pp. 124-125. Works numbers were 367-370 in 1863.
Locobase 20701 describes the Province class as originally delivered in 1863 by Beyer, Peacock. After 17 years of service on the Ulster Railway and its successor, the Great Northern Railway of Ireland, the former UR shops in Belfast made over all four.
As a comparison of specs would show, the rebuild increased most key specs. Boiler pressure went up by 20 psi (1.38 bar), more tubes of a smaller diameter (1 3/4"/44.5 mm vs 2"/50.8 mm). Heating surface area increased by 93.4 sq ft (8.68 sq m). The new engines had a flush-top boiler, centered dome and Ramsbottom safety valves on the firebox. Previous visible leaf springs over the drivers were now hidden behind solid splashers.
Once modified, the class gave more than 25 years of additional service bedore Ulster was scrapped in 1909. Munster followed in 1912 and the Connaught in 1913. At the time of LM's report, the Leinster had only recently left service.
