   • 1952 September, Norman Crump, “Camden Town Signalbox, London Transport”, in Railway Magazine, page 585:

     Alternatively, they clear when the line is unoccupied to the next signal and when an approaching train occupies a short, normally de-energised, track circuit on the approach side of any of the signals. These normally de-energised track circuits are labelled with a Greek letter to emphasise their difference from the normal track circuits, and are short enough to ensure an adequate restriction of speed being imposed on the train.
