DWWR 15

Dublin, Wicklow and Wexford Railway number 15 of 1860 was the first of a number of 0-4-2 tender locomotives built by Sharp Stewart, which was the only supplier of the 0-4-2 type to the railway. In total twelve were supplied in batches in 1860, 1864 and 1876. They were considered a mixed-traffic type, and in practice the railway mostly used the locomotives with the higher tractive effort of 15,520 pounds-force, which were about two tons heavier with 17 by 24 inch cylinders and 4 ft 9 in driving wheels, on main line freight, and the others on mixed passenger and freight trains. The 0-4-2 type was made obsolete from 1895 by 0-6-0 and 2-6-0 types.
