All the locomotives produced of this arrangement have been tank locomotives, and the vast majority in the United States. It was a popular arrangement for the larger Mason Bogies , as well as some of the largest suburban tank locomotives.

The locomotive was mostly used in the Boston and Albany Railroad.
