The Highland Railway Jones Goods class was a class of steam locomotive, and was notable as the first class with a 4-6-0 wheel arrangement in the British Isles. Fifteen were built, and one has survived to preservation. Originally known as the Big Goods class,^[1] they became class I under Peter Drummond's 1901 classification scheme.

Fifteen locomotives were built by Sharp, Stewart and Company and delivered between September and November 1894, numbered 103 to 117. At the time, these were the most powerful main line engines in the country. Originally intended principally as freight engines, they were often called upon for passenger duties during the wide fluctuations of traffic which occurred on the Highland Railway, particularly during the summer season.
