They shared many parts with other standard classes, although less so with the heavy 4-4-0s on account of their lighter build; instead, they shared some components with 0-6-0 switcher classes F and H (later B1 and B2 ).[ 3]
The Class G locomotives had a straight-topped boiler, unlike the wagon-top of the other 4-4-0 classes.
