The ACL (Atlantic Coast Line) was interested in a locomotive with more steaming capacity than their 4-4-0s. In 1894 Baldwin designed a conventional 4-4-2 locomotive for the ACL and named it after them. Other railroads bought and called these locomotives "Atlantics". However, the Brooks Locomotive Company gave the name "Chautauqua" to this wheel arrangement. Also, Chicago, Milwaukee, St. Paul & Pacific (The Milwaukee Road) used the name "Milwaukee" for this wheel arrangement.
With 178, the AT&SF owned the most of this wheel arrangement. However, the 4-4-2 was probably made most famous by the Milwaukee Road when they built four very large streamlined versions of this locomotive to pull the Hiawatha. These locomotives were the first built streamlined and were designed to cruise at 100 mph.
