Axle configuration definition
Axle configuration means a code of the form AxB where A represents the total number of wheel positions available on the vehicle and B represents the total number of wheel positions where tractive force is applied by the vehicle powertrain. Thus, for example, 6x2 represents a 3-axle vehicle with a wheel positioned at each side of the axle (six wheel positions) with one driven axle (two driven wheel positions). Extended axle configurations considering further subvariations are included within the basic characteristics. Substituting a number for an X means it represents any number. For example, 10xX includes any axle configuration with five axles.
