In the computer era, we too often lose sight of the physical properties of the components making up an electric locomotive. When we go from one component to another, for example from the tapchanger to the thyristor, the physiology of a locomotive is completely changed from both the electrical and the mechanical viewpoints. Not enough attention is given to the alteration undergone by a locomotive in its service life (for example, the wheel wear) and also because of operating decisions concerning the differences accepted in service between the diameters of the wheels on the same locomotive; and these decisions are not in fact independent of the electrical diagram of the locomotives. Also, the calculation of the loads which a locomotive will haul is not as obvious as the locomotive purchase contracts lead one to believe. All these questions are not the province of the constructor alone, but the combined manufacturer plus user, and the latter's influence is considerable. This paper shall therefore summarize what a user has observed during his career in the design and utilization of locomotives.
