              The Federal Railroad Administration (FRA) contracted Transportation Technology Center, Inc. (TTCI) to expand on existing mechanics-based ballast condition forecasting models. This report demonstrates how one of the mechanics-based models performs against field data and makes recommendations for improving that model.
