Locomotive Magazine, June 1919

The Cambrian Railways class 89 comprised 15 0-6-0 freight locomotives designed by Herbert Jones. The first five were built by Robert Stephenson & Co. in 1903. Another five came in 1908 from Beyer, Peacock & Co., which had longer cabs and a slightly larger boiler. The boiler was the same as on the 4-4-0 class 94. The last five followed in 1918 and 1919 from the same manufacturer. From 1924 the GWR began to fit the locomotives with new boilers in Swindon. After one had left service in 1922, the others followed between 1952 and 1954.
