The projects' general objectives include supporting research by way of data collection to improve railway safety, performance, and efficiency. Projects supported may include, but are not limited to, tie/rail/wheel lifecycle studies, vehicle dynamics, wayside safety systems, emerging technologies, laboratory testing, and sensor calibration efforts. These projects may include support of the Facility for Accelerated Service Testing (FAST), general commercial, and Strategic Research Initiative (SRI) testing programs, instrumented wheelset builds, perturbation measurements, and calibration projects. These projects may be funded by the Association of American Railroads as part of MxV Rail's Strategic Research Initiatives program, through the Federal Railway Administration (FRA), MxV Rail's internal research and development, and/or commercial customers.
