The effect of the increase in line speeds on the overhead current collection system is a matter of concern for British Rail, particularly in terms of the quality of current collection and the wear of both the overhead wire and the carbon collector strips. This project is concerned with an investigation into the wear performance of existing collector materials, by the refinement of an existing wear machine used to simulate railway conditions for the contact materials. The development of a data logger and a high resolution method of measuring copper wear for the wear machine are described, and the results of the contact strip wear tests are presented and discussed. Also included is a survey of the recent developments that have been made in the field of current collection, with particular emphasis on railway practice.
