ABSTRACT: This report summarizes the Federal Railroad Administration (FRA) project to design and fabricate an advanced self-propelled track geometry inspection vehicle (TX). The TX effort involves FRA contracts DOT-FR-9088 with the Budd Company for a Budd SPV-2000 diesel railcar, and DOT-FR-9112 wich ENSCO, Incorporated for a computer-based track geometry instrumentation system. The MITRE Corporation under Contract DOT-FR-54090 has provided a wide range of technical support starting in 1976 with assistance in preparing the requirements analysis, the statement of work and the specification through technical monitoring of the final systems tests and review of deliverables. Major features of the TX include a totally self-contained system, substantially improved reliability, improved measurement accuracy, . expanded utilization of digital processing and increased system productivity. The first of the TX series of vehicles, the T-10, is capable of measuring track gage, curvature, cross-level, warp, profile, and alignment at one-foot intervals at speeds up to 80 miles per hour The project was completed on schedule and within three percent of the estimated budget.
