Scope
Description: Traction power systems experience some of the most extreme variations in local power loads as compared to most other large scale electric power supply networks. These variations create challenges in the construction of reliable electric power delivery systems and in the performance of the rolling stock dependent on power supplied by the system.
A method for defining the electrical load supplied by a nickel-cadmium battery and for sizing the battery to supply that load is described in this recommended practice.
Description: The electrical interfaces among the components comprising the auxiliary power systems and their electrical interface with other train-borne systems are described.
