This report describes the investigation and implementation of changes performed by Transportation Technology Center, Inc. (TTCI) to improve the efficiency and capabilities of the current Positive Train Control (PTC) braking algorithm evaluation methodology for freight operations. Improvements included: simulated cases with an addition of PTC enforcement warnings and enabling analysis of the results with a railroad network model; a determination of whether additional granularity is needed in scenarios that represent common industry operations; and modified the simulation process to increase simulation efficiency, which will decrease time and labor to complete PTC enforcement braking algorithm evaluations.
