TRA performed Triennial Safety and Security reviews of these rail systems in 2005 and 2009, including in-depth assessments of Metrorail and Metromover system safety, accident investigation, corrective action response, employee safety, configuration management, vehicle maintenance, infrastructure maintenance, employee training, operations management and supervisions, substance abuse testing and compliance, and all other areas covered under state and federal regulation. TRA auditors performed in-depth interviews and assessments on-site and provided MDT with detailed findings and recommendations. In addition, FDOT asked TRA to assist in assessing MDT’s proposed corrective actions to safety and security issues. Under separate contracts to District 6, TRA also provided technical assistance on behalf of FDOT in response to a fatal incident involving MDT rail service and an employee safety concern.
