The NZR X class was a pioneering class of eighteen 4-8-2 steam locomotives designed by A. L. Beattie that operated on the national rail network of New Zealand. In 1908 a heavy and powerful locomotive was required to haul traffic on the newly completed mountainous central section of the North Island Main Trunk Railway and as a logical progression of the 4-6-2 Q class design the 4-8-2 wheel arrangement was created for the X class.
