Highland Railway Clan Goods Class

The Highland Railway's Clan Goods class was a class of steam locomotive. They were designed by Christopher Cumming. The first four (Nos 75 to 78) were built by Hawthorn Leslie and Company on Tyneside, and the maker's plates bore the date 1917, but because of wartime delays were not delivered until 1918.[1] Four more (Nos. 79 to 82) were built in 1919, also by Hawthorn Leslie.[2]
