THE Pacific type or 462 locomotive is usually associated with the first engines of this wheel arrangement built by the Baldwin Works for New Zealand early in the twentieth century. However, some few other locomotives previously had such wheel arrangements, among which were three compound engines built by the Rhode Island Locomotive Works. These were for the Chicago, Milwaukee & St. Paul Railroad in 1893 and designed for fast passenger service.
