In the Whyte notation for describing steam locomotive wheel arrangement, a 2-6-6 is a locomotive with a two-wheeled leading truck, six driving wheels, and a six-wheeled trailing truck. 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 Denver, South Park and Pacific Railroad.Robertson Donald B. https://books.google.com/books?id=-aWhRfr3rdkC Encyclopedia of Western Railroad History 1986 Caxton Press 978-0-87004-385-7 37 enPoor Meredith Clarence https://books.google.com/books?id=aHLVAAAAMAAJ Denver, South Park & Pacific: A History of the Denver, South Park & Pacific Railroad and Allied Narrow Gauge Lines of the Colorado & Southern Railway Company 1949 Rocky Mountain Railroad Club 466 en It also saw usage in New York and Chicago.Kalmbach Media Company http://archive.org/details/2022-03-01-classic-trains Classic Trains - Spring 2022 2022 18–21
