A catenary is a system of overhead wires used to supply electricity to locomotives and electric trains equipped with a pantograph. The electricity is delivered via the pantograph to the high speed circuit breakers and thus distributed to the different required systems. This study focusses on integrating a catenary tracer system that assesses the condition of the catenary wire (overhead wire) for maintenance decision making. The system consists of a laser scanner and data acquisition box mounted on the roof of the train, and speed sensors mounted on the bogies. The system is designed to continuously collect data from the catenary wire, to assess and to detect defects on the catenary wire. The data is analyzed and classified in three different defect categories; Yellow class - to be corrected during routine/preventative maintenance or to be corrected during standard B maintenance in the vicinity; Orange class - Conduct maintenance not later than 6 months and Red class – indicating danger, and closure of section for immediate attendance. The collected data is then loaded to the depot server and compared to a reference to determine if maintenance on the catenary wire is required. The assessment of the catenary wire leading to various maintenance decisions forms the focus of this paper.
