ABSTRACT: This report describes an approach to evaluating the reliability of human actions that are modeled in a probabilistic risk assessment (PRA) of train control operations. This approach to human reliability analysis (HRA) has been applied in the case of a safety evaluation of the Communications-Based Train Management (CBTM) System being tested by CSXT Transportation, Inc. This report describes the overall approach to the HRA and its trial application to the CBTM evaluation.
