The Federal Railroad Administration (FRA) contracted Transportation Technology Center, Inc. (TTCI) to conduct a broad analysis of the impacts of Positive Train Control (PTC) systems and technology on track maintenance. This research was conducted between September 2019 and September 2020. This report documents the activities of the effort, including a review of the project objectives, an overview of PTC systems and technology in the context of track maintenance and roadway worker protection (RWP), and an analysis of the potential areas that PTC might affect track maintenance. In coordination with FRA, TTCI generated a list of possible effects of PTC on track maintenance to guide the research.
