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[edit]

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]

History[edit]

The last engine was scrapped in 1941.[1]
