The automated freight classification yard electromagnetic environment is composed of electrical and electronic devices that are each potential sources and/or victims of electrical interference. The electromagnetic radiation of the environment and selected railroad yard devices such as doppler radars and switch machines was measured at three railroad classification yards. The susceptibilities of selected yard devices were measured to determine operational sensitivity to the yard electromagnetic radiations. In addition to yards, since railroad electrification has important implications, radiations from an electrified railroad operating at 50 kilovolt 60 Hertz were also measured to formulate a measurement methodology and to determine the potential interference effects on railroad operations.
