 With the grate automatically stoked via a tender-mounted conveyor screw and blower motor, it was now possible to harness the full steam-raising potential of the locomotive's boiler without the stamina of the fireman being a limiting factor.The steam requirements for both engine and booster were able to be met for unlimited periods at maximum steam pressure even against the action of both injectors.Comparative performance tests with black coal-fired X30 revealed that X32 was able to generate a drawbar horsepower output of at , exceeding by 5 to 10% that which could be produced by X30 with good quality Maitland or Lithgow coals.
