              Transportation Technology Center, Inc. (MxV Rail) conducted a project for the Federal Railroad Administration (FRA) to complete the development of Operational Performance and Reliability, Availability, and Maintainability (RAM) Analysis (OPRAM) tool. The team successfully developed the OPRAM software tool according to the objectives established in the scope of the project along with the associated documentation and training. The software is easy to install and operates as a standalone application in a desktop environment. Railroads can use the OPRAM software tool to assist in decision-making in defining when and where to deploy new methods of train control, per the Higher Reliability and Capacity Train Control (HRCTC) Program (i.e., Enhanced Overlay Positive Train Control (EO-PTC), Quasi-Moving Block (QMB) and Full Moving Block (FMB)). This support is provided by a direct comparison of different deployment options, prioritizing incremental enhancements of these train control methods as they become available, and evaluating and comparing potential RAM enhancement options.
