The Z21 class (formerly L.304 class) was a class of steam locomotives built for the New South Wales Government Railways in Australia. [2] [3] [4]

Wheel arrangement

The wheel arrangement for the Z21 class was 2-6-0. Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels.[ citation needed] This arrangement is commonly called a Mogul. [5][ citation needed]
