Data from "4-6-0 Tank Locomotives, West Clare Railway, Ireland", Locomotive Magazine, Volume XXIX [29], No 368 (14 April 1923), pp. 94-95. See also Roger Farnsworth's repost of a 1951 Railway Magazine article "The West Clare Railway - Part 1 - Ennis to Corofin" at [], last accessed 18 November 2021. Works numbers were 1432 in October 1922 and 1433) in December.
LM's report commented that the Hunslets had "clean run lines and generally presents a substantial and workmanlike appearance. Given the narrowness of the 3' (914 mm) gauge, the bogie arrangements came in "for careful consideration on account of the severe curves." Unusually for West Clare locomotives, this pair used outside radial Walschaert's gear.
Tested and approved, the engines awaited "more settled conditions" before entering regular service, biding their time "locked up for preservation." When they emerged from their cocoons, the West Clare almost immediately came under the control of the Great Southern Railway in 1925.
Ennistymon was scrapped in April 1953, Malbay lasted until February 1956.

One of four Ten-wheeler tanks that the "never very prosperous" (OS Nock, RWC IV, pl 17) railroad bought over 14 years. This engine was Bagnall's works #1881.
The three other tanks, supplied by Hunslet in 1912 and 1922, were very similar but had 45" drivers (See 5083). All lasted into the mid-1950s.

LM explained that Ireland's light railways were "very far from being easy for locomotive work", particularly because the railway followed the contours of the land to reduce construction costs. A challenging profile--including a 3-mile (5 km) stretch of 1% grade--and a strong increase in demand prompted locomotive superintendent W J Carter to design a more powerful engine and order it from Hunslet. Its outside frame afforded the most space possible between the wheels for boiler and firebox.
Like the Kilkee, the engine saw out steam on the WCR and was scrapped in April 1953.
Two later engines -- Ennistymon and Malbay (works numbers 1432-1433). -- were supplied in 1922. Malbay actually was the property of South Clare Railways.

This engine (works number 818) enjoyed the longest service career of any West Clare engine, heading for the scrapyard only in 1952. It was named for the then-popular seaside golfing resort, which also was near the 700-ft cliffs of Moher.
West Clare's data showed a firebox with 79.5 sq ft of firebox heating surface and a total evaporative heating surface of 700 sq ft.
