Almost everywhere where track circuiting is used. It is the basis of
Victorian and South Australian signalling (TransAdelaide excepted). QR,
Tasrail (ATN), TransAdelaide and Westrail all use British "Route"
signalling. NSW uses a one of a kind bizarre system invented by NSWer's and
only understood by NSWer's. Go figure?
