WASHINGTON - The U.S. Department of Transportation’s Federal Railroad Administration (FRA) today released a quarterly status update on railroads’ self-reported progress, as of June 30, 2020, toward fully implementing positive train control (PTC) systems by December 31, 2020, as required by Congress. Based on railroads’ Second Quarter 2020 PTC Progress Reports and current PTC Implementation Plans, nearly all railroads subject to the statutory mandate are operating their systems in revenue service or in advanced field testing, known as revenue service demonstration (RSD). As of June 30th, PTC technology remains to be activated on approximately 700 required route miles.
