Many thanks for the explanation, and FWIW, the eddy current electrical power meter you mention was one of Tesla's inventions (which surprised me when I discovered the fact).

On another note, what is the longest practical length a track circuit can be when using 100 hz (cycles per second) and still have reliable occupancy detection?
