Under the Whyte notation for the classification of steam locomotives, 0-2-2-0 represents the wheel arrangement of no leading wheels, four powered but uncoupled driving wheels on two axles, and no trailing wheels.[1] Some authorities place brackets around the duplicated but uncoupled wheels, creating a notation 0-(2-2)-0.[2]
