Transportation Technology Center, Inc., as part of a project sponsored by the Federal Railroad Administration, evaluated the safety and operational performance of the Enhanced Automatic Train Control (E-ATC) braking enforcement algorithm and found it exceeds previously established safety objectives, but also may introduce operational inefficiencies. The evaluation was performed using a simulation methodology over a broad range of operating scenarios and equipment used by railroads deploying the E-ATC system.
