Well into the Machine Age, when cast iron foundries and machine shops were as common as weaving mills and breweries, the narrow gauge locomotives had many folks involved in their creation and development. The wheel arrangements were many and varied, not so much for pulling power and speed as for the capability of the rail and support systems. The smallest possible wheel arrangement (prior to the imaginary Smokey Stover Fire Chief car or the modern gyro-stabilized Segway) was the 0-4-0 and the 2-2-2, the middle number(s) being the number of driving wheels, capable of pulling only minimal consists (in the later years the 2-2-2 served as the power plant configuration for VIP and inspection cars) lightly rolling on small rail and primitive roadbed. The largest was the 2-8-2 and the 2-6-6-2 that required significant infrastructure but could pull dozens of car consists.
