ACCURATE PREDICTION OF OVERHEAD LINE BEHAVIOUR

Various attempts to model the dynamics of current collection from an overhead line have failed because theoretical predictions were not adequately supported by experimental data. Using scaled-down catenary, British Railway's research team has been able to obtain good agreement with computer prediction of dynamic behavior, at the same time keeping the complexity of calculations within bounds by identifying variables such as contact wire bending stiffness that have little practical effect on current collection. Improved pantograph designs for use with existing equipment may be followed by cheaper electrification of low-speed freight and urban passenger lines.
