A bit of history

A 4-4-2 Locomotive refers to the classification of locomotives under the Whyte notation for the classification of steam locomotives by wheel arrangement, where 4-4-2 represents a configuration of four leading wheels on two axles, usually in a leading bogie with a single pivot point, four powered and coupled driving wheels on two axles giving tractive effort, and two trailing wheels on one axle, usually in a trailing truck which supports part of the weight of the boiler and firebox and gives the class its main improvement over the 4-4-0 configuration.

This wheel arrangement is commonly known as the Atlantic type, although it is also sometimes called a Milwaukee or 4-4-2 Milwaukee, after the Milwaukee Road which employed them in high speed passenger railroad uses.
