Abstract:The electromagnetic environment in classification yards has become more complex due to the widespread application of electrical and electronic systems and is characterized by the transients of collapsing electrical fields of heavy equipment such as switch machines, retarders and traction equipment. Such noise levels affect the low level signals used for control, signaling and communications, particularly those utilized in automation and for data processing. FRA has sponsored a project to identify this environment and its preliminary results are reported.
