Research on Methods for Enhancing Positive Train Control Freight Braking Algorithms
The Federal Railroad Administration (FRA) sponsored a research project, executed by Transportation Technology Center, Inc. (TTCI) to investigate methods for enhancing the data used by Positive Train Control (PTC) freight braking algorithms and to improve the evaluation process of PTC freight...Locomotive Performance and Engine Durability Assessment of B5 to B20 Biodiesel Fuel Usage
This report summarizes work performed by Southwest Research Institute (SwRI®) to investigate the durability of several locomotive engine components under various blends of biodiesel from 5 percent biodiesel (B5) of up to 20 percent biodiesel (B20). Due to changes in the U.S. diesel fuel...Positive Train Location: Final Report
The overall goal of the Positive Train Location (PTL) project is to develop a system capable of providing the onboard PTC system with timely and accurate position reports of the head-of -train (HOT) and the end-of-train (EOT) for determining track discrimination and train length without the use of...Positive Train Control Track Data Auditing System
The Federal Railroad Administration (FRA) contracted with Transportation Technology Center, Inc. (TTCI), to develop documentation for a system which automates the auditing of railroad track data for Positive Train Control (PTC). TTCI developed a Concept of Operations (ConOps) document and...
