The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classification of locomotive axle arrangements (based on counting either the axles or the bogies).And why do the European use UIC and the US uses Whyte notation?

Why are there three different ways to specify the wheel arrangement on train?
