Data from "Six-wheels Coupled Goods Engine, L T & SR," The Locomotive & Railway Carriage & Wagon Review, Vol IV (July 1899), p. 109.
Acquiring 6-coupled freight locomotives was an "entirely new departure" for the L T & S, according to the author, who forebore (or possibly did not know) that these were orphans. They were originally ordered by the Ottoman Empire's Turkish Railway, then cancelled. Up to that time, and beyond to the amalgamation of the L T & S with the Midland Railway, the pair would be the only engines with a separate tender. Once on the Midland, the locomotives would be refitted with Belpaire fireboxes. They were carried into the London, Midland & Scottish in 1923 and served until the 2898 was scrapped in 1933 and the 22899 (as it was renumbered) in 1936.
