Abstract
The paper covers the practical measurements made, by London Transport, on the levels of induced current in track circuits produced by conventional and thyristor-(chopper-) type traction equipment on their 4th-rail traction supply system. The method of measurement, the subsequent method of analysis and the implications of the results are described and discussed.
