The Federal Railroad Administration (FRA) first-quarter 2020 update on railroads’ self-reported progress on fully implementing Positive Train Control (PTC) by the Dec. 31, 2020 deadline shows that, as of March 31, 2020, the job is 98% complete. 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), with PTC technology remaining to be activated on only approximately 1,100 required route-miles.
