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 established a set of high-level requirements from which to design and implement a Track Data Auditing System (TDAS). The TDAS is designed to utilize machine vision sensors to capture georeferenced data for PTC critical assets and support the auditing of PTC track databases. This ensures track data used by the PTC system accurately represents the actual location and attributes of assets in the field that are critical to train operation. Using the ConOps and the system requirements, a Request for Information (RFI) was developed and delivered to vendors. RFI responses revealed significant gaps between the TDAS requirements and available technology.
