The first use of the name American to describe locomotives of this wheel arrangement was made by Railroad Gazette in April 1872. Before that time, this wheel arrangement was known as a Standard or Eight-Wheeler. This locomotive type was so successful on US railroads that many earlier 4-2-0 and 2-4-0 locomotives were rebuilt as 4-4-0s by the middle of the 19th century.
