Test operations are being conducted on the 7.7-km (4.8-mile) Facility for Accelerated Service Testing loop at the Transportation Test Center. The 9000-Mg (10,000-ton) test train operates 16 h/d at an average speed of 67 km/h (42 mph). The goal is an accelerated service test of track and rolling stock to determine comparative performances, wear rates, and maintenance and life-cycle costs. The consist is composed of 90 rail freight cars prepared in accordance with test specifications. Of the 90 test cars, 76 are available each day for testing. At least 1 year of test operations is planned. Four cars are removed daily from the cost for a 24-h period of test measurements and data collection. Inspection and gauging of components common to all cars occur every 22 d. Measurements of specific test components are made in accordance with the objects times during the test period so that a wear rate can be established for each component. The components involved in these experiments include wheels, journal roller bearings, adapters, trucks, springs, center plates, side bearings, brake shoes, wear plates, and couplers. The experiments and test measurements on each component are described.
