Abstract:

This paper is the first of a two-part series describing a ; research project, sponsored by the Federal Railroad ; Administration (FRA), to study the structural integrity of joint ; bars. In Part I of this series, observations from field surveys ; conducted on revenue service track are presented. Automated ; and visual inspections of rail joints were conducted to identify ; defective joint bars. Detailed information and measurements ; were collected at various joint locations. ; The survey team consisted of personnel from ENSCO, Inc. ; and Transportation Technology Center, Inc. (TTCI), working in ; cooperation with staff from participating railroads. Part II of ; this series describes the development of finite element analyses ; of jointed rail, which is being carried out by the Volpe National ; Transportation Systems Center (Volpe Center).
