A livery override block offers the option to change the look and behaviour of a wagon depending on the engine it is attached to. It is basically the same as a graphics-block, except that it only applies to a particular combination of an engine and a wagon. E.g. passenger wagons could adapt their livery to match the engine, to make the consist look like a multiple-unit train. The spritegroup needs to be defined before it can be used in a livery override. A livery override block is always part of the engine definition and looks like

livery_override (vehicleID) {
	spritegroup_name
}

For an example see the spritegroup
