Improperly trued wheels increase rolling resistance, reduce energy efficiency and may create unsafe operation. A railroad wheel typically consists of two main parts: the wheel itself, and the tire around the outside.
They also don't calculate the rolling resistance of such things as flat spots on wheels, lateral motion of cars, open boxcar doors and head and cross winds. Open boxcars doors create a great deal of drag.
