The status of two foreign rail technologies is analyzed in this report. The two technologies are Wheels and Automatic Couplers. The wheel development program for the French TGV is reviewed. It illustrates the application of classical wheel design to modern high-speed rail transport. The resilient wheel and its reduction of effective unsprung mass is studied; the SAB resilient wheel application on British Rail is reviewed. Lightweight axles are also discussed. The review of automatic coupler technology is primarily concerned with the latest coupler designs from both the mechanical and electrical train-line concepts. The evolution and development of advanced couplers in the United States and Europe are covered.
