Industrial 0-4-0 Locomotives in Ireland


Class Details by Steve Llanso of Sweat House Media

Class Standard 14" (Locobase 6455)

Data from RN Redman writing in the Industrial Railway Record (September 1965), which is archived at [link] (viewed 27 Oct 2004). Redman explained that the earlier saddle-tank design was upgraded by increasing the cylinder diameter by 2", and extending the water tank the full length of the boiler. This smoothed out the line as well; the photograph shows a compact locomotive with slightly inclined outside cylinders supplied by inside valve gear.

The prototype appeared in 1929, but the next order didn't come until 1935. Most were produced in the 1930s and 1940s, with six more delivered in the 1950s.
