After Drummond's departure for the Glasgow and South Western Railway in 1911, Smith was appointed to replace him, albeit under the old title of Locomotive, Carriage and Wagon Superintendent.[1] His only design for the Highland Railway was the River Class, which was rejected by the Chief Engineer, causing his resignation. He went on to take a post in the Ministry of Munitions and in 1918 entered the steel industry.
