The purpose is to document training practices at a sampling of transit agencies concerning the application and repair of advanced on-board electronics so that key personnel have the knowledge needed to make informed decisions. The objectives of the synthesis were to examine the level of E/E training being provided by transit agencies to highlight innovative and effective training approaches and, based on findings from the conclusions, to provide agencies with the opportunity to improve their training programs. Because maintenance is an area that is often overlooked, this synthesis gives it the greatest focus.
