Abstract: The Association of American Railroads (AAR) computer program for rating steel railway bridges is extensively modified to analyze and rate trusses under any type of special train loading other than the conventional Cooper ...

Abstract: The design and performance of an active controller for a pantograph which collects current for a high-speed train are considered. A dynamic model of the pantograph/catenary system is described ...

Abstract: High-performance pantograph design requires control of pantograph dynamic performance. Many pantograph dynamic models developed to aid in the design process have employed two degrees of freedom, ...
